Ok, you guys found me!!
I have 17x8 w/ 5" bs and 17x10 w/ 5" bs (narrowed rearend) and use a 245/45 and 315/35 tire, with this combo both side walls are the same at 4"...something I had to have!! This is the widest tire you can run on the front with a stock subframe and not have the tires rub the frame at full lock. Also, the 315 is the widest tire that comfortably fits under a '67-'68 camaro (without rolling the fender lip)...in my mind 335s only clear the wider fenders on the '69...but hey that's just my opinion, but it is based on the thought that if a tire EVER rubs, it actually doesn't fit...again, just the way I see it.
What back spacing did you order? Can you do the full DSE Deep Tub with a convertable and keep the top mech.? I'f it makes any difference I cleared my 315s with just a 2.5" tub not the ever so common 3" tub.
Here is Joe Sears' car he has a 255 up front but basically the same setup as what I have.
Hey sweet wheels by the way, I love the Famosas, I actually almost got the Fontanas but then found a great price on my Pentias...so that's what I went with...you'll love the Budniks they are great quality!!
