They may have tread for 300 laps, but doesn't mean they will have grip for that long.

If your planning more sprints and hill climbs, the softs would still be the go I guess.

I mean they last that long :) But apparently had grip all the way to the canvas... In saying that it is probably bias info :P

I've had my medium V70's since June 2012 and did....

rest of 2012 - 4 race meets (some meets had either 4 sessions (1 X qual and 3 x race) or 8 if I double entered (giggle)

2013 5 race meets and 2 of them I had doubkle entered again (MX5 and superTT)

this year1 hill climb and sprint

so they lasted very well!!!

they also had about 300kms of road use give or take.

Wow nice effort! So they are certainly worth the money :yes:

I've run both the mediums and hard V70a on the GTR and was happy with them. Just bought another set of mediums the other day for hillclimbs

I found the mediums were destroyed on a 20 lap race on a hot day though, the hards were fine for sessions up to an hour without undue wear. And they grip very well long after the visible tread is gone (it is designed to wear off early in the tyre's life, the wear indicators are on the 2 main grooves).

I have no experience with their softs; but I would have gone them for hillclimbs if I could of got them...you can't have too soft for a hillclimb

Also one thing to keep in mind with these, on the GTR and GTSt at least, they work best at 44psi hot. I tried them at both 42 and 46 and they were slower.

Yeah sorry I don't believe that every racing team in the world was wrong. Hectic drifters want stretch because 1) narrow tyres are cheaper and 2)it is a fashion and that is about the only people who do it.

I'll stick with the widest tyre I can fit on a given rim size except for 2 cases:

Assuming I understand what i've read - I think your focussing on the wrong bit. Yes, the widest tyre that will fit within the wheel well and past the suspension components is the best, however, you should put that tyre on the widest rim that is approved for that size tyre.

FWIW, here's pics of 265s on 10.5 inch rims, for those concerned with aesthetics;

I'll second that. I gained almost time and a whole bunch of "feel" changing from 9" to 10" wheels with 255 semis (which measured 270) on my old 180SX. They were pretty bulgy on the 9s and gave no feedback near the limit - very snappy. On 10s they were slightly stretched, heaps more progressive on the limit and faster at both QR and Lakeside.

Interesting feedback! I run 265 on a 9" which measures about 280 and they felt OK, in saying that i have nothing to compare against so if i find some wider rims ill see if i can notice a difference.

Probably been done to death but after a tyre on which I can drive 400 kms, do a hill climb and sprint then drive 400 kms home on. Seeing as the events are in Albany in the middle of winter there is a distinct chance it will be cold/raining. Not after the last word in competitive R comps (have some A050's for proper stuff) but was wondering if there was a decent S tyre tyre or similar that I could use for this trip and as a roadie thereafter.

Falken RT615.

Kumho KU36.

Yokie AD08R.

Other suggestions?

Scrap the Faulkens, I have them, they are crap, the K version is suppose to be better but have heard any proof yet

The Kumhos are good as an alrounder, no complaints from me about them, except the AD08s are way better and worth every cent they cost

The yokie AD08s I currently have on my 32 are by far the best road tyre I have ever driven on

The hankook RS-3s I currently have on my 34 are a really really good tyre, slightly better the KU36, but just not quiet as good as the AD08s

I am keen as mustard to try the Achilles 123s next as I believe they are going to be a really good tyre and for the price they are impossible to beat value for money

  • 2 weeks later...

my take on these street-track crossover tyres is that anything that costs as much as cheaper semis is pointless - buy the semis! So for me that rules out AD08, RS3 and R1R. If you really have to have the fastest tyre over 120 UTQG reagardless, WTAC pre-control tyres pretty much proved its the RS3. And they should be cheaper than AD08 too.

Otherwise that basically leaves the choices down to KU36, RSR and 123S if you're looking for something cheaper than semis that will do an OK job on the track and road..

RSR are the fastest of the rest but wear out so quickly that buying semis works out to be better value.

KU36 - I've had these on a Supra and Legnum. They do respectable times and can cop an absolute flogging. They were quiet on the Supra but noisey on the Legnum. They were good in the wet imo, but many disagree with that. 180 treadwear. These lasted as long as normal road tyres on my Supra and did heaps of track days locally and interstate. I wouldn't hesitate to buy these again.

123S - all i really know is the Excel racers do pretty respectable times on them. 200 treadwear and very deep tread - might be a bit squirmy at first but they should last pretty well. Sidewalls seem nice and stiff too. I just put a set of these on my Datto yesterday. The main reasons I chose these over KU36 was that he had them in stock and gave me a pretty sharp price on them.

Well the A050's are $520 each and the KU36 were out on special from Tempe tyres at $250 each. I was going to buy them but I noticed that their special of free shipping didn't include anyone who lived outside a capital city. So I ditched that and will probably get them from the local shop as by the time you add freight and fitting there is nothing in the price.

Either that or some AD08R's if I can find them on special at some point as they are $400 each.

Just needing a road tyre than can do an occasional hillclimb. Basically they are for driving to the track more so than on it. 600km worth of travel to/from the track and four degrees neg camber don't make for a long lasting tyre.

Edited by djr81

Personally, I reckon if you're after a tyre that's more for driving to the track than on it, you'd be better off running less camber too, so the car matches that ethos as well. You won't need 4degree camber on a crossover tyre, it will be better on the track and road with less camber.

Hankook RS3 are cheaper and faster than AD08Rs. But if you're looking for a tyre more for the drive to the track than on it, KU36 or 123S will be the ones that last better on the road and cost way less than AD08R. You can even get R888 or NT01 semis cheaper than AD08R, and they won't last much less on the road than AD08R.

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
