ST Coils, 1" Drop: 17x9 will +35 poke?
 

I think I'm finally coming into the home stretch as to what wheels I'm going to get. I recently got ST Coils and dropped my car 1" (would've gone more, but NJ potholes are NASTY).

Now I'm considering the RPF1 17x9 in +35 offset, this should sit pretty flush with my setup right? Or am I looking at some poke and need a bigger offset?

I checked the tire/wheel calculator page and it -looks- like the +35 should be fine, but I was hoping for some confirmation.

Thanks.

you should be fine as long as you dial in some negative camber.

+1

Ok, here comes the newb question...I only got the coils, no camber/caster plates or LCAs.

Am I able to adjust the camber without those items? Should I just go with a bigger offset?

Sorry for my lack of knowledge, I'm still filling in gaps.

Thanks.

Front should be adjustable, but if you want to go more, install the camber bolt. Either OEM or SPC. Rear is not adjustable, you need LCA.

I lowered my car 1 inch on springs and my rear cambers are 1.9.

You can adjust the front camber around -.7 to -1.4 degrees (or so) with inexpensive crash bolts or camber bolts.

The rears you cannot adjust, but after a 1" drop will get about -1 to -1.5 degrees of "natural" negative camber so they should tuck nicely.

Use the calculator here to check.

ST coils have slotted holes for your bolts in the front, so no need for camber plates. Ask the shop to give you negative camber in the front when getting an alignment.

Your rear should see between -1.8 to -2.1 degrees of camber with a 1 inch drop.

Hope this helps.

Thanks for the info folks.

I did before. I plugged in the numbers (17x9, +35 offset, -1 ride height, 0 camber) and the tire size I plan to use (245/40r17) and according to the calculator the rears should actually be just a slight bit sunken in, while the fronts are about dead flush.

So I wanted to check-in to make sure.

I'm on the exact same rim/tire size with you with the same 1" drop. You should be good.

i have 17x9 +38 with 245/40/17 tires. 1" drop with hotchkis springs.

rear camber (non-adjustable) came to -2.0 degrees.
front camber with whiteline adjustable camber bolts maxed out at only -1.3 degrees.

from the top view (looking down at the wheel from fender), my wheel is aaaaaalmost flush (pokes about 1mm). with a +35 wheel, you'll be poking just a tiny bit more unless you can get more camber dialed in.

I'm curious to learn from all that are running this setup as well since I want to run this exact configuration with either Volk TE37Vs, Weds TC105ns, or Enkei RPF1s. With "natural" camber maxed with the assistance of camber bolts, seems to be close to flush but curious if you rub if you hit a dip on the freeway (esp in front) seems like rolling of the fenders may be a good idea. To me 17x8.5 +35mm square may be the more perfect size (from a performance perspective) since you probably won't rub at all.

I'm running 18x9 +35 and no issues at all. Overall tire diameter is the same, only difference is the tire is closer to the perch on the 17" setup whereas the 18" wheelrim is closer on mine.

My camber settings are -2.2 front and -2.0 rear with Eibach ProKits lowered by 1".

No LCA's in the rear but crash bolts in the front (hole widened for a bit extra camber).


To the OP, you won't rub at all. With the 1" drop, you'll gain enough camber to tuck those tires in. Great tire & wheel combo, will be my track setup shortly.
