The Roush 18x10s are 41mm offset.
Why is this not in the tire/wheel forum?
$179 for 305 r888?
Where?
If your budgets alittle looser then try some Enkeis or the BBS race wheels from Ford racing or if your ready for the big leagues Forgeline, Jongbleods or CCWs
...just received my Griggs Severe Duty LCAs and UCAs for my GR350 65 fastback. I'm building my 65 with full (front/rear) Griggs.
Did you call Roush yet?? We already know their 18x10 45mm wheels will fit on the front and rear with 275 tires with no problem. They would also know best if a 305 would would clear since they run a race car in the Koni (now Continental) road racing series.
Roush Forged wheel 18x10" does not have enough clearance beyond 275 width in front. 295 in rear with no problem though (tested). Its heavy and I would not recommend it for tracking.
Thats why I bought Enkei 18x10" with 38mm offset. Now all around 295/35.
Can you provide photos of your Enkei 18x10 wheels with 38mm offset on the front and rear with 295/35-18 tires? Which Enkei model did you purchase?
Here is the summary:
Wheels are RFP1 18x10" 38mm offset
Tires are Nitto NT05 295/35 R18
Wheels clear for big calipers with no problem at all. I do have Stoptecs. My friend (GT500) got same wheels accommodating 6piston Wilwoods.
At Front I have -2 camber so the wheels do not extend beyond fenders at all. I didn't have any clearance issues apart of under sharp turning my wheels scratched custom made brake cooling pipes which resulted in hissing sound. Those are from some kind of anti fire fabric. My mechanic took care of it.
In rear the wheels do exceed the fenders by 2mm on each side. I think 285/35 are perfect match for our cars with this offset and rim size.
please find pictures attached and excuse the quality I took it with my iPhone.
Cheers,
Jan

Almost seems like your on a hopeless quest..You want to fit 305s all the way around..on budget wheels and resort to very little mods.Jan,
Thanks for all the great information. I'm still trying for fitment of 305 for the track. It seems that the 42 or 45mm offset wheels that I find will fix the 2mm issue on the rear. I'm still working on calculating the front fender/strut clearance. I am surprised by the 38mm offset and front fender clearance...I guess the negative camber solves that issue.
Now for the big favor...any chance you can turn your front wheels out to the stop and take a pic of the clearance between the wheel/tire and strut? If you could use a tape measure to show the clearance, like my attached photo, I would appreciate it...It's been hard trying to find someone actually running a 18x10" wheel on the front.
I agree that a 285 or 295 would be great, except that the Toyo RA1 come in 275 or 305..no 285 or 295. At the track, I would be running more negative camber than -2 so it seems that outside fitment won't be an issue. My issue will be strut clearance.
Thanks!
David
You are correct the Roush Forged wheel is 18x10" 45mm offset. I was able to fit maximum 275/40 to the front with that setup. To be honest it was no problem as Roush stage 3 suspension is made for it.
After switching to Steeda adjustable coilovers (Tokico based) it became an issue as wider tires were gently touching the struts. Since then with above metioned Roush Forged wheels I run front 255/40 and rear 295/35 Invos as commuter wheel/tires setup.

Not to give you greif...Sorry
Why not either stick on some rather cost effective 275/285 tires on 18 by 9.5's or 18 by 10's like most people and get some stickier (more sticky then ra1s) tire like Hoosier or Hankooks?
OR install some Hoosier R6/A6 in the 295s sizing that will fit a 9.5 like Sam has
That way, the tires are always gonna be there..you'll have alot of sizes to choose from and you won't have clearance problems
Or spend the $$$ and get custom wheels made or buy a SLA for the front.
I tried cutting corners for awhile in my car..waste of time and $$$..
