Mate I have no problem driving my car without breaking traction, It will never be a Dyno Queen as it was never built for that, It's a Built street car with a few social duties at the drag strip. Lets not turn this thread into "Look how big is my dick is" I love Soarer as much as you guys, that why where here right?

I started this thread to discuss tyres, as I would like to put more power to the ground if possible. I don't expect to put new tyres on the car, get 30000km out of them and have perfect traction in all gears, but if I can buy better tyres that will hold on better I will buy them. As for driving it in the rain, I won't, I have another soarer for that. Back on topic guys. Thanks to your suggestions I've been looking at tyres I never would have.

Hehehe

I like the idea of mickey-t's cam, maybe you should give the track a whirl in winter?

I've got a customer thats going for the new/upgraded e11 = the 2000 series from Haltech. I forgot to mention today on the phone that this was out. The new software package allows knock retard by the looks of things, hopefully i'll get a good play with it over the coming weeks to iron out any bugs. THey've also 'upgraded' the tuning interface quite a bit, so its a lot faster and smoother in 3D - and colour coded. Looks a lot like Motec's tuning interface where table are modular and independent from the main window so you can throw them around easily and neatly over several tabs.

My point, a whole lot better than the microtech :0 How did the workshop owner put it again; "its an electronic carburetter"

Its not the amount of power giving you the problem, its the way its delivered. Your big single 1.5JZ has a powerband that just dumps whopping torqe in the space of not even 1500 rpm.

Gee I really hope I don't have this dilemma with my t04z 1.5jz. I really don't. Oh gee that would be horrible. The horror....

ok. im the guy with the 350rwkw supra. basically running 255 advan neova's ad07's i cant get grip in 4th when i just put my foot down. I have been drifting on these tyre and even at full lock, spinning at top of 3rd i have enough traction to push me towards to apex every time. but that doesnt help my straight line traction. thats where throttle control comes on. the bridgestone s03's in 275's had bugger all traction to.
Your better off learning to control your right foot better.
Had 225/50/16 semi slicks on a a70 with 250rwkws and without having throttle control you could spin the rears just hitting boost in 3rd aswell.
learn how to drive. or get less power. or better yet... buy a excel and have this as your dyno queen.

people saying get semi slicks and slicks is just a waste of time, every day driving will kill these within 5k kms anyway and for the cost its not worth it.

hehehe you read my mind...

James, Cams last dyno output;
I tuned this for a soft midrange because from experience anything over 7500N on the street with the soarer auto in 3rd is not tyre friendly.

I haven't drive a 350rwkw soarer but I have driven a few around 300. Yes traction is an issue but from what you describe I think you can do better.

Springs rate seem ok but with that much power you might be having excessive suspension travel thence change in camber reducing the contact patch. Ie a slightly harder spring could be optimal.

Depending on your aims cornering or straight line grip I would reduce the camber as much as possible on the rear to insure under load maximum contact patch is maintained. I have heard of some people using positive camber on the rear with very soft springs ie factory springs in some applications to maintain optimal contact patch under load.


Look at a really good set of tyres. PS2's RE01R's ect. I am currently looking into the RE01R's as they are supposed to be grippier rubber with less void area and slightly softer side walls. In theory they will flex and deal with the sudden load placed on them slightly better and with more grippy rubber on the road they should hang on better.

I would suggest going for a resonable width tyre pending on your rims but 255 would be what I would target in a really sticky street rubber ie a tread wear rating of around the 180 to 200.

Remember a if you use a wider tyre you do not get extra rubber on the road but exactly the same contact patch area just a different shape wider but shorter.

Damian has made a few valid points.

Reducing camber and a softer spring rate will help traction. Also, run 26 psi in rear tyres not your turbo.lol

No street tyres will grip at that power. My boosted stock twins fry 1st and second with 285 yokohama advan sport which is one of the softest compound street tyres you can get. Semis dont launch too well either. As others suggest MT streets are your best bet and learning to control the throttle a bit.

Bobby how much power are you putting down with stock twins.

I have driven TT's with high 200's ie 280rwkw and with good tyres they stuck no problems in a straight line.

I was going to ask the same thing. 285s are a fairly wide tyre..
