Default 345mm tires on an FBody

I am doing a mini-tub plus associated suspension, hopefully by the end of the year, and I am thinking of widening my TT2s and running Toyo 345/40r17. I am also considering new wheels and 345/30r19 or 355/30r19.

Inputs? Any pics?

Other than the cool factor 345's are huge on these cars. I've ran 3 sets of OEM C6 Z06 wheels with 325 30 19's on rear. Just had bfh, tubular rear lca's, rolled fenders, trimmed bumpstop bracket. No spacers

I found this thread with pics of an F-Body with Toyo Proxes 345/40r17
https://ls1tech.com/forums/forced-in...ytp-build.html

Hopefully, I can get these on my widened, factory offset TT2s after the mini-tub. My 315's on 17x11 TT2s from WS6store stick out too much for my taste.

All the oem C6 Z06 wheels had a +50 rear offset on the 19x12's so you don't need spacers unlike the base C6 wheels which had like a +72 Or so

Stock F-Body rear offset is +55, right?

No need to mini-tub to fit 345 tires...............

I have my 335 tires on 18 x 12.5 rims....they will fit fine after we cut the steel ridges away from the inner wheel well wall. Offset LCA's and some hammering.

I already bought the mini-tubs. Plus, if you got 335s under there, then I should be able to fit 345s and have the tires flush with the fender. My 315's stick out a too much for my taste on 17x11s.

My 335's are actually about 15mm inside if the fender. I bought 15mm spacers to bring them outward so they will be even with the fender. I should have about 3/4" of space on the inside of the wheel well wall when its done.

Depends on how I like the look of the Toyo 345/40r17s. They have a larger contact patch than the 355/30r19s.

Hey 2JAWZ. I have a quick question for you. I have a 2001 SS with tubular lower control arms. I have a chance to pick up a real nice set of 2013 Grand Sport wheels with tires. They are the 18x9.5 +40mm fronts with 275/35/18's and the 19x12 +59 rears with 325/30/19 's. Other than the BFH mod and fender rolling for the rear what would I need? Do the fronts need spacers? Thank you and your car looks awesome.

Tubular lower control arms, bfh, cut bump stops, and if you dont like to hear it rubbing from time to time center your rearend with adj panhard bar.

18x9.5 285x35x18
19x12 355x30x19
OEM C6 Z06 rims but any of the widebody vette rims will have this look. Base model has different offset and rim width ect ect.

fronts dont need any modifications
camaro could use spacers in front to sit flusher to fender, the TransAm fenders aren't as wide and sit perfect.

rears for both cars needed fenders rolled , tubular lower control arms, adj pan hard bar, 1/8" spacer, cut bump stops and you named it BIG FREAKIN HAMMER MOD lol if anyone has any questions just let me know, I dont go on here often but always available on my instagram account
@LSX.JAMES 🤙🤙

ps both cars are on stock springs/height, and the pictures of the ta were taken without the suspension settled. And as you see when rolling it's pure perfection
