Ive got a Turbo GSR that will make 400+whp.....I need some help on wheel and tire setup. Lightweight wheel? Wider? Size? Anything would help. Ive read threads from top to bottom and I cant find anything clear for my Goal. This is a street car. Just looking for a little direction. Thanks to all that respond

Tires. Tires. Tires.

If you don't have an LSD yet, get one. Step one. Stepping up to a 205 or 215 width tire will also help, but forget about all seasons - you need summer tires if you want to keep grip. If you don't already have some kind of solid or polyurethane-filled mount, get them - wheel hop sucks, and good mounts help prevent it.

The greatest tires in the world won't help you if your suspension setup and driving abilities are absolute ****...

Layzboy713

So you suggest running a OEM wheel/decent tires but then buy an lsd?

I would never try to put down 400+whp on a 215 tire. At minimum you'll need a 245, a 255 would be optimal but that requires specific wheel fitment, ride height, and fender massaging.

I just installed MT ET Street Radials 225/50/15 on my Daily 500hp LSV, and there great. 3rd hooks, 2nd will hook at 3/4 throttle. Oh and my car makes almost 400ft lbs of torque @ 5k rpm

As a street car, though, it won't actually see all 400 of that horsepower. Of course it'll rip any tire that isn't a drag radial, but a good 215 summer tire would hold well enough to drive on when the weather agrees. A 245 would be better...but good luck getting one to fit, and still be driveable.

I ran 400whp daily drive for years on a 205/50/15 all season Falken ZE912's Its all about how you manipulate the power and setup the car. boost by gear and a lot of fine tuning of that will be your friend. you do not need super wide tires. i was able to hold full power with gsr transmission and LSD 3-4 gear and less power in 1-2 gears but thats just FWD reguardless of what tires you have

Good suspension, stiff motor mounts, good tires, and boost by gear. I'm currently running nitto neo gens in 205/50-15 and they hook every gear with bbg properly setup. Its really nice to smash the throttle in any gear any time and always hook! I make about 300whp and run mid 12s with 2.0 60ft times on these tires. They also only cost $284 for all 4 shipped to my door. I also ran these tires on my old turbo integra gsr and would dead hook 360whp in second gear as long as it wasn't too cold outside. If I was going to step up to more tire I'd personally get the toyo r888 in 225/50/15.

Tire size depends entirely on what he's doing with the car.

Any car used for drag racing can use a smaller tire as long as the tire provides enough grip out of the hole. After 2nd gear it doesn't matter much anymore due to gearing (torque multiplication), downforce, weight. Etc.

If he's using the car as a daily that might see a mountain run or two then he absolutely needs a wider tire. Seeing as how lots of twisty roads are 2nd and 3rd gear at relatively low speeds with lots of g forces and a high amount of torque being applied to the wheels he will spin all day long depending on how aggressive his driving abilities are.

Whereas a strictly street car doesn't need a lot of rubber since under typical conditions he won't be able to put a high load on the tires.

Personally I always go wider because my street cars see lots of aggressive mountain runs and lots of track days at road courses.

It all depends on personal preferences.

As far as the work needed to fit wide rubber...

Assuming you have a reasonable and functional ride height and the proper offset and width wheel then fitting something like a 255/40 is as easy as a good fender roll and pull.

A friend of mine runs 275s on his road course EG hatch that makes around 435hp and he's still using stock body panels with a small flare at each corner.

how much does a traction bar help out?

Traction bar reduces deflection in the suspension. It helps with wheel hop and keeps the control arms from jerking forward somewhat and gives you caster adjustability. At minimum I would recomend changing out to energy suspension bushings. It's a good upgrade and helps control some of the deflection. Sphericals are the best route but costly. The most important one is the compliance bushing. New run complete kingpin outlaws on my integra now and the car hooks a lot better at the track and the suspension is solid and has a much better fluid motion instead of binding with rubber bushings.

I don't even bother trying to hook on the streets mainly cause I don't and wont street race. Good ol' Kumho 205 Ecstas for me.

LightningTeg

R888's for street use. Myself and several other 500whp + guys on here swear by them
MH 235's if your just drag racing and dont mind riding on pillows and the affect they have on your final drive
Nitto neogens if your sub 500whp and need something that will work year round.

Layzboy713

So what about wheel size?

NotARaCist

iTrader: (1)

Not that big of a deal. 15" is the diameter you want. Width, I'd personally stick right around the 7" area, so you'll be able to properly mount decent sized tires without having to do any wacky offsets or dumb "hella" bullshit.

I had GREAT success with Toyo R888's. In fact, I now own my third set.

The first set I had was 225/45/16. In 70+deg weather, they spun 2nd gear at 450whp, stuck about 580whp in third, and 650whp in fourth/fifth.

I then moved to 225/50/16. They would just haze 2nd gear at 450whp, stick 620-630whp in third, and hold all 700whp in fourth/fifth if temps were above 70deg or so. I did my last roll racing event with these tires in 38deg weather @ Pocono Raceway, and with the cold temps, they wanted to spin 18psi or so boost in third, but held all 30-32psi in fourth/fifth.

I recently grabbed a set of 15" wheels, and picked up a set of 235/50/15 R888's. It's waaaaay too cold to give my impressions, but they are only a little smaller than the 225/50/16's I had before, so they SHOULD fare pretty well.



I would like to note that traction on street tires is all about how torque is brought in. Honestly, a car that has some boost creep (intentional, or not) usually makes for a good-hooking FWD car.

LightningTeg

I concur. I have the 235/50/15 set now on 15x8's

wantboost

iTrader: (2)

the 235/50 is a good all around size IMO. It just takes a little fender love to get them to fit depending on ride height

LightningTeg

Yeah I had to roll on fenders and about 2 finger gap

Spunkster

Hondata also offers Traction control.

D-Rob

Indeed they do!

BUT! The traction control isn't meant to cure all traction problems, only to realistically fill in the gaps!
