Whats the specs on those 18x11s? Offset? Backspacing? Thanks.
You would have to contact CCW for that. Its whatever specs they use for the 03/04 Cobra wheels.

Id love to see rear end pics of those 11's
Best pic I have at the moment. 335s will be going on soon so Ill be getting some better ones. I know 335s will stick out a bit farther but I might be able to sneak a small spacer in there as well if I need some clearance or want the wheels out a little bit more.

The rear is for sure. Not happy with the fronts so Im thinking about going back to the stock cut front coils and maybe taking a bit more off. From certain angles the fronts looks great but when I get close I can really see the height difference. The first side profile pic is with the cut stock springs up front. These pics I just posted are Steeda Sport springs on all 4 corners. Thanks again :beer:

Jefe, i am pretty sure those are CCW wheels, am I correct? If so, I was looking at CCW wheels. I will be putting HR race springs on to lower. If i were to get 11" wide rims, i would be looking to put 335/35/18 tires. know if I would have the clearance with the spacer and low pro irs bolts? i'm not the most knowledgable about offsets and what not. so i could use all the info i can get. thanks

CCW Classics. 18x9.5" front & 18x11" rear. No one makes a 335/35/18, only a 335/30/18. With a spacer and low profile bolts you shouldn't have any issues. I'm gonna try and fit 335s without a spacer. CCW sets up their wheels specifically for the Cobras so we dont have the fitment issues most have

ha! learn something new everyday. and thats awesome to know that ccw is a perfect fit. did you have to make any mods to the front to fit those rims? without knowing, my cobra came with crappy cobra r replicas and i went to rotate the wheels one day and the rear wheels were like a half inch wider than the front and when they put them on the front, the wheel cut the abs wiring. when i got that fixed, the mechanic said he moved the wiring on both sides so that wouldn't happen again. did you have to do something like that at all?

FYI fellas, the approved rim width for a 335/30R18 is 11.5-12.5. So 11.5 is the bare minimum width.

The max tire for an 11.0 inch rim is 315/30R18.

Manufacturers spec wheels and tires for a reason.

Not telling anyone what to do, but whatever you decide, please consider keeping safety in mind. We are on the road too.

I have CCW sp500's. 18x9.5 in the front and 18X11 in the rear. I run a 315/30/18 tire in the rear with the irs bolts without any fitment issues. Matter of fact these wheels fit better then the 17X10.5 stock Cobra wheels I had on there before I moved to 18's. The CCW's tuck in better without sticking out. As for the 18X9.5 fronts they fit without any modification.

I have the same size ccws as Jefe, my backspacing is 6.75" rear and 6.25" front. In installed the low profile irs bolts when I mounted them for safety, but I didn't need them. Running 315/30/R18 Michelin PS2's.

So, yes they will fit.

no spacers with the 18x11's? the sp500's are the ones ill be aiming for. pricey but soooo worth it. what size tires are you running in the front with the 9.5"'s?

I am running 275/35/18 Michelin PS2's up front and 315/30/18 Michelin PS2's out back. No spacers out back. I am very happy with my CCW's and to top it off they have great customer service.

I don't run spacers with my true forged wheels but did install low pro bolts even though I didn't need to. Rears are 11" wide with 335's.

Wow that sucks. No mods whatsoever right now besides Caster Camber plates for the alignment

Well my rims are 11" but if you measure from lip to lip(which is where the tire seats), they are actually 12". Not sure on Cobra rims but I imagine they should be the same.

Awesome. Which tires? Any pictures of the clearance? Assuming TF and CCW set up their backspacing the same
