Those look great!
I have these sitting in my office waiting to mount up. I ordered the 17 x 8 size, they are called the Ridler 675. Very happy with the price ($512 & free ship) and the appearance!

I put 8's on the front with 245's and 9's on the back and squeezed in 285's..Love the wheels and the ride is night and day with the extra rubber on the ground.

I have these 17'' staggered wheels on three of my GTO's. They are awesome. The best tire combo is made my Continental. Its 285/40R17 in the rear and 275/40R17 in the front. They fit perfect. And Continental is a great tire.

How did you fit 275's on the front? I could only get 245's in with without any clearance issues, wish I could have went wider. I went with the Nitto 555's.

The 275/40R17's fit perfect on the front of my 70 and 71 GTO's no alterations necessary. I had to roll in the front fender just slightly to make them fit on the 68.

Came across your post. Can you tell me your tire sizes for front and rear? Also, did you have to roll the fenders or cut the lip to fit these in? Thanks

So I would like to change from 15's to 17's but I'm worried about traction, I'm running about 500hp 550tq and it's hard enough with 275/60 drag radials to keep it between the ditches when I pop the clutch. I'm going to try and make some more room in the wells and maybe a 5" backset to try and fit some 305/45/17 in but drag radials aren't the best for handling and I'd like to keep a 28" tall tire to keep the rpms at a decent number, also would like an American name on the tire, just feels strange with a big Japanese lettered tire on my American muscle car...I know I'm weird like that. So what's everyone's opinion on something like that for good street traction?

Also Bumping this thread. I have a 68 gto clone convertible... looking to switch it to 4 wheel Disc. Currently has 14" Rallye I's
Option 1 easy choice: get 15" Rally I's and then most disc kits will fit (what disc kit? is another thread lol)

Option 2. 17" Year One rally II's I'm thinking 17x8's all around But i have no idea what offset 4.5" or 5" ???? no idea what I should get.

If you go with the Rally II's, the 17x8's come with a 4.5 inch backspace and the 17x9's come with a 5 inch backspace. That is what you see on my car.

FWIW my 68 has 17 x 9 all around. No issues with rubbing etc. IIRC I couldn’t get 17 x 8’s at the time which I would have preferred. With the fast ratio power steering mod the ride is vastly improved over the 14 x 6 OEM Rally 2‘s that it came with.

Mickey Thompson ET street.

Mickey Thompson ET street.

That's what I got, I guess they're big enough because I tore up my differential at the track 😉

I guess they are sticky enough! At my mild RA2 build - 380hp, I do not have that problem. it'll light up the P245/60/15 Radial TAs just fine though.
