17x9 Wheels on stock suspension
 

Hey guys, I've checked wheels directory, but can't find much info for stock suspension except what offset is flush if there is one. I started autocrossing a month ago and the biggest downfall in the car (except for my skill) is the grip and I want to combat it with good wide tires on wider lighter wheels. I like Enkei TS9s, but not sure if 17x9 will fit, otherwise I'll get 17x8.

If anyone has ever put 17x9s on STOCK SUSPENSION please let me know what wheels and what offset? If not possible please let me know as well.

Thanks!

You will be fine depending on the offset of the wheels. +35 offset on 17x9 will clear the stock suspension and will not poke out like an eyesore. +42 is fine as well; however, I would be wary to push it any further.

Hey thanks for the reply! As the offset on those is 45 I see 2 options, 10mm spacers in front (backs supposed to be flush at 42 offset) or getting 17x8 in front (but i'm not sure it won't upset the balance). What would you suggest? I'm new and young so might ask stupid questions :)

What's your rulebook say about wheel size? SCCA bumps you out of CS for a wheel size change.

Alignment is a pretty important bit too - its what keeps the tire contact patch where it needs to be to grip.

If you have plans where to go with the car and mods where this change fits in the grand plan, great. Otherwise, you may find yourself wanting something different.

Future plans include only coils and sway bars ATM. I'll check the rulebook.

17x9 +35 Offset will fit

Fronts right? Rears 45 should be good I believe referring to the wheel fitment guide.

17x9 +38 with 245/40/17 tires all around fits no problem also. barely clears the stock suspension, but still clears and no rub even on hard turns.

+35 square.

+45 is more sucked in

How much front camber are you running?

when i was on stock suspension, camber was whatever it was straight from the factory which was minimal. im on ST coilovers now and lowered just over 2inches. -2 front, -2.7 rear

17x9 +45 will work fine on stock suspension as long as you don't add any more negative camber (though it would be beneficial if you did).

17x9 +42 will work fine and will allow you to run slightly more negative camber than factory.

17x9 +35 will require you to run -2ish camber up front not to rub (but don't be afraid of the camber as it will help with tire wear if you are autocrossing.

Just FYI, I had to run a 5mm spacer on 17x9 +42s with -3.2 degrees of camber to clear the springs (Swift Spec Rs but should be the same diameter as stock).

17x9 Wheels on stock suspension
 

17x9 +35 will clear stock suspension or eibach/trd...

+45 you're going to have to be on coils.

I have 18x9.5 +45 and also 17x9 +35

Stock is 17x7 +48

Hey guys, thanks for all the responses! I got just a bit lost, some people mention springs and camber. Might sound stupid but can I adjust camber on stock suspension? And for the springs, do I need to get some specific ones? I was thinking about getting a a bit shorter stiffer springs before coils (coils are a plan for probably next summer).

Can anyone please sum up what do I need to get those wheels on? I know camber will be beneficial for autocross and not afraid of it (as long as it's reasonable and performance oriented), so -2 sounds perfectly fine.

Thanks everyone!

I ran my 17x9, +35 for a while on stock suspension with no issues. You can get a little more negative camber up front by purchasing OEM crash bolts that go in the upper slot. I think I got about -1.5 at the time, but it can vary a bit depending on each individual car. Rear camber is not adjustable unless you have aftermarket control arms.

Springs are not necessary to fit the wheels. I think it'd be a waste of money since you're planning to get coilovers in the future anyway. Save the money on springs to get the coilovers faster.

...or you can save even more money and just get good tires on the stock wheels. You'd be amazed at what tires alone can do, even in stock size. Something in the Extreme Summer category, such as Hankook RS3, Dunlop Z2 Star Spec, BFGoodrich Rival S, or Bridgestone Potenza RE-71R.

Also, if you actually want to improve/learn driving skill, don't go super wide and super sticky too fast. That'll just mask any driving mistakes and you won't be learning car control as much.

You will not be able to make any camber adjustments to oem suspension w/o any additional parts.

You can get camber bolts for the front-- find a good alignment person/shop and get them to dial in as much camber up front as possible w/ the bolts, keeping the toe straight (or adjust to whatever suits your taste). You won't be able/need to do anything to the rear if you're on completely stock suspension.

So I'll just go all-in next summer and get wheels, tires, coils and sway bars next summer and currently make do of whatever stock can offer. Thanks a lot!

Is it worth doing for stock and if I plan switching to coils for next season? Thanks!

Yes, the bolts are only like $10. You can even use them on some coilovers depending on which ones you get.

17x9 +35 Is the perfect fit on stock. +38 high chance of rub on front strut. I have been running RPF1s 17 x 9 +35 with RE11a Have tracked 9 days, great handling.

Im thinking about getting 17x9 wheels for my frs. Is there really a big difference between +35 and +38? Used for daiky driving so whichever will give me more peace of mind with no rub

running 17 x 9 +35 with 245/40/17 running -1 up front and -1.75 in the rear. I have had no rubbing issues and it has been 60k miles.
