Dropped my car in to Belconnen Discount Tyre Service this morning, and amongst other things whilst chatting with Mark (top bloke, really knows his shit) i saw my new 255/35/R18 Dunlop SP Sport MAXX's off the rims.

WTF

They are f**king huge. I mean, i used to look behind Boxsters and 911's and go, wow they are big tyres - f**k no move over. By Huge i mean they are comparable to my Forearm (i'm 6 foot 3).

Also got him doing a wheel alignment and looking over the suspension to see whats there, if any of the bushes are shagged and grease it up.

Top bloke - knows what he's on about, owns a Stagea, and will look after you.

tires arent cheap, 300ish for Federals the new type and they are quite good. Except now i am wheelspinning coming on boost in second might need some new ones.

$430 ea for Dunlop SP Sport MAXX's, 255/35/r18, to put things in perspective, the fronts (235/40/R18) will only be $315ea.

wider tyres = more drag on long journeys = increased fuel consumption.

you should have thinner tyres for everyday driving and just use the wide ones for track days. better yet get semi-slicks :rofl:

I'm actually in a bit of a pickle at the moment in regards to rims;

I want a new set of rims but I'm not keen on dropping down tyre width from 255 to 235s which most rims these days seem to take.

Is there really that much difference when it comes to tyre width?? Obviously the more tread I have the better grip I get and fuel consumption isn't really a concern of mine but is 20mm going to really impact me?

Depends on the quality of the tyre you're using I reckon.

The cost of an 'ordinary' 255 width tyre might be the same as a really good 235 width tyre. The 255/40ZR17 Nexen N3000's that came with my mags when I bought them are nothing short of utter shite at the retail cost of $190 each, which is cheap for any brand's "top of the line" tyre. As a (bad) comparison, the 225/50ZR16 Falken Ziex 512 tyres I had on my old 16's absolutely shat on these Nexens from a rather great height in every way.

Even the 205/50R16 Vredestein Sportrac 2's I had on the front 16's had much better handling than the 225 Nexens I have now.

I suppose what I'm trying to say is instead of spending money on a new set of wheels with some normal tyres, get some decent tyres for the mags you have and you might end up better off.

I'm fairly sure that the wider the tyre you using on the front will give you heavier steering, which you may or may not want. I quite liked the difference in steering feel my car had when I went from a 205 to a 225.

Honestly it depends on the tyre.

If you go from say nankings or hankook k104's or nexens, to say High end dunlop, yoko, goodyear stuff - irregardless of size, you will notice a world of difference, assuming you have it properly aligned.

The New Dunlop SP Sport Maxx's i have on my rears are unbelievable for traction even though they are barely scrubbed in. Even over the K104's i had before they started doing scrubbing problems.

I remember the red widebody R33 GTS-T that Parvis used to have in the F&F imports showroom(the old location)that had 335 section tyres... F**K me;huge!

That car was a beast... And we actually took the rear wheel off the car..

IT was SOOO BIG!!!!!! The front wheels were a 10 inch rim, and the rear was 12.5 i believe!!!!

for the price of a set of 255s you can get much better 235s, as bluprint is suggesting. this is particularly the case since commondoors take 235s and the economy of scale makes them cheaper. add far wider choice and it's a win both ways. add to that less tramlining and smoother ride; unless you're dragging, in which case wider might always be better, i'd rather go for good 235 than an average or unknown 255 anyday. just my 2c.

    • The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.
    • Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.
    • Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks  
    • Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..
    • I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.
