Track rims? Size?

[fookah]

Im planning to do a track day but curious on what tires and rims to use.

I am told that 13s would be better but would have thought 15s would be better to firm the ride up. stock are 14s.

WOuld be running the car on semis so whats your thoughts?

Thanks

After a few trackdays on my car (stock 16"), I would prefer 17" wtih a low profile tyre as the sidewall would flex less.

Why dont you run your car on some good street tyres first?
You save money and that way when you run semis you will know how many seconds exactly those semis gave you over street tyres

Thats what i thought but then using 13s with semis would have a harder side wall.

my street 14s have fairly soft walls

I would go at least one size up from stock, less sidewall flex and it will make a difference in your cornering capability.

get 15's if u had stock 14's, 13's will have 2 much tyre wall and will flex like the others have said.

[tinkerbell]

use 15's with 50 series R specs like R888's

205/50ZR15

^^^ exactly what i run at the track

Why is everyone recommending rims and tyres without knowing what car this guy has?

Unless you have some experience I would not start with semi slick tyres. A sticky street tyre will serve you better.

As some have said, if you've never tracked before, just try it first on your stock rims and tyres (doesn't matter if your tyres are wearing out).

Find out if this is really your thing before blowing money on new wheels and tyres.

For your stock streets, just pump it up to around 40psi cold

Depends if you can fit 13's. If you have a stock EG with the stock calipers and rotors, 13s will clear it fine. I've ran 13inch semi slicks on the track with my last EG and still got some decent times.

sorry guys, car is a swift gti.. turbo charged. car already sways alot as is with tires on atm (195/60/14) and have a lot of traction with 150+ kw hence wanting semis.

Stock tire from factory are 175/60/14, ive put 195/60/14s

suspension has been done with springs, shocks, sways and strut braces

he said it comes stock with 14in...

unless it is a freak car, a +1 fitment would be a 15in with 50 or 60 series...

since the toyo 205/50R15's are so common - that is why i recommended them...

and since the topic is not "should i run semis or streets", i stayed on topic.

Fair call. Sorry I missed the "stocks are 14s" part :p.

15s are the go then. No need to worry about brake clearance especially if the OP wants to upgrade to bigger brakes in the future. Plenty of semis in 205/50 15 but that is a little taller than stock, which might be a good idea to slightly lower the overall gearing if you have a fair bit of power.

Bridgestone RE55s come in a 195/50 15 which is a bit closer to stock diameter, and they are a decent tyre.

yeah, the 195/50R15's might be better on a swift? but maybe not if it is a fully high-po one...

[fookah]

yer that was what i was thinking.. 195/50/15s

[hoey888]

if your turboing and wanting to track your car, have you considered using a 7" wide rim and using 205/45/16?... you'll be surprised how much a difference a wider tyre and lower profile tyres can do for your ride

[fookah]

car is already turboed.. im guessing 16s will be too big and will have scrapage also tire wall will be too small to absorb bumps. and going too big of a rim would effect the gearing also.

Widest rims that will fit in the guards, with smallest diameter that will fit over your brakes - less mass and tyres are cheaper in smaller diameters.

Narrow (i.e. stock 6") rims make sidewalls feel floppy, go wider before you band-aid it and go bigger. Big rims and tyres add much sprung weight, you'll hate it on a light car.

Gearing is usually not a factor since you can change the tyre profile to keep the same rolling diameter.
