i gotta buy new tyres for rego an thought since im dishing out money i may as well get tyres that dont spin everytime i hit boost. what have you guys found to be the best street slicks, an if you have any links to supplyers web pages?

there are known gotchas when using semi slicks on the street - buyer beware

you obviously have some issues if you are have that much traction issues - i suspect there are other issues

semi slicks are approved for American roads, not australian. may get away with it, maybe not? and absolutely no good for the wet

why are they no good for the wet? have you ever driven on some? what about wet weahter specific semi slicks? isnt the tread only in the tyres for wet weather driving anyway? im no tyre expert but ive driven an FC3S with wet weather specific bridgestone potenza 595 S something semislicks in the wet and they were mental

and also correct me if im wrong, but dont the lotus elise and or exige that are available as a road going vehicle in australia come out of the dealership with advan nevoa (not sure of the exact model) semi slicks?

yes they do, but that doesnt make them good in the wet :glare:

better off going for a tyre like the kuhmo ecsta

obviously this would be better in the "Suspension, braking and tyres " subforum :D

I used to drive around on semi's all day and every day.

they are legal for on the road as far as i'm aware, as they are dot approved,

in the wet, it was often hard to lose traction in a 450hp gtr And in the dry... forget about spinning your wheels anywhere, even 7000rpm launches all you got was stick.

Now the bad points,

They will be alot harder on your drivetran, you could possibly even break things, your diff is going to get a worn out alot quicker and the tyres themselves dont quiet last that long..

this was bridgestone re55s or similar.

These guys give me 1.54 60 foot times and are street legal, so they are my everyday tyres. Just be careful with skids as i have used a pair in 8 quarter mile passes showing off. They come in plenty of sizes too. More grip in the wet than my old street tyres because of the compound gripping, but as i dont run them on the front aquaplanning is not an issue.

They don't like corners very much, but great in straight line.

federal 595rs or falken azenis rt615 seem to get good reviews... treadwear rating is like 180-200 for both so not too low. also they'll disperse water better which is good for a street car.

Don't use semi slicks on the road.

Why?

Because they are, in no particular order:

Noisy.

Stiff in the sidewalls which gives you a harsh ride.

Expensive.

Short lived.

Pick up every stone etc on the road & fire it into your paint.

And, um oh yeah A WASTE OF MONEY

A semi slick needs temperature to generate its grip properly. Other than driving like a complete fkwit on the road you will not generate these temperatures.

So you will never get the gain out of the tyre you wanted.

Just go and buy some good road tyres.

yeh the camber on my rear wheels is out, im gonna buy ajustable camber arms of ebay http://cgi.ebay.com.au/REAR-Upper-Mount-Ad...1QQcmdZViewItem

have any of u guys used these items before? what do you think of them?

As is quite common, the traction problem is not tyres. The usual suspects, lowered too much, too high a rear spring rate, no rear subframe alignment or camber correction. Simply replacing the upper control arms will only partially fix one of the problems and introduce yet another, bump steer. You need to correct both the rear upper control arms and the traction rods to avoid bump steer problems. There are better alternatives for fixing this problem than replacing the arms, try a Rear Camber Kit from Whiteline or Noltec.

true to that Sydney kid...

I recently did a full comprehensive alignment on my 180SX at Wholesale Suspension after I installed new bushing in the front end on my own and decided to align every part I on the car.

Just after the alignment alone, I noticed less bump steer, more grip, less to zero tyre squeal around corners and mind you this is with just shietyy yokohamas.

For street use, don't bother with semis, unless you're going to track it, I would save the money and get offset bushing to correct camber on the front and rear and get a good alignment.

i.e. don't bring it to Bob Jane, or your mainstream shops, they're not capable of adjusting camber...

I asked, they said they couldn't do it.

They can do it just fine. Once you tell them you don't care about tyre wear and you won't be back in 2 weeks complaining about bald inner edges they will do what ever you ask for.

My local bob jane adjusts my front and rear toe, front and rear camber and front caster. I wouldn't expect them to have the time or the gear to corner weight or adjust traction rods so i don't ask. It's the difference between $500 and $50 alignments

back on topic. I run rs595's on the front and rt215's on the rear. It's a waste of money, except for the odd time i get to the track and it's too wet for proper semis. If you have an aggressive alignment you will destroy the things driving on the freeway anyway.

As mentioned by djr, don't run a proper semi on the street either, they need heat to work properly, when they aren't hot they are worse than nankangs and will have you up a gutter before you know what happened. It happened to me when i was young and naive, i have a $250 rim repair bill around here somewhere to remind me not to be so stupid in future ;)

    • I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.
    • Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
    • Well they got my money but they are not getting my gearbox ! 
    • It's needed for rolling idle up, and I think it is a decider on VCT also.
    • I mean, not really. Link ECU's can absolutely still have errors from the ECU thinking it's getting a sensor it's not expecting. I would imagine the speed at the ECU level in Nistune does absolutely nothing anyway? I assume the ECU does not do any fancy TC stuff with regards to front+rear wheel speed or anything of that like anyway. Someone who uses Nistune may be more fluent in it.
