Can anyone tell me if 17X8 with 4.750 backspacing and a +6mm offset will work on my 86 TA front and back? What size tire would be best? I want to order them today and I want to be sure I'm getting the right size. Thanks

 

anybody?

 

245/45/17 is stock diamteter, and will fit.

the wheels will fit, 4.5" of BS would be better, but 4.75 will still work.

 

I have 17" x 9", 0 offset Snypers. Sorta..... I HAD that front & rear, but fit 11"s in the back now.

Your wheels are 1" narrower but have the 6mm difference in offset. That is just under 1/4" so.........(i hate conversion crap! )....You essentially have 4.75" bs.

In other words...They should bolt straight up with zero problems. In fact, even better than mine (which had zero problems, btw), since they would sitting a 1/4" further out.

Anybody wanna double check my math?

 

he HAS 4.75" of BS, nothing "essential" about it.

everything else is fine, they will bolt right up.

 

Calculator say 4.73", which is why I said "essentially".

 

Thanks for your reply's guys!! I appreciate it greatly!! Will they look ok on the car with 4.75 or should I go with the 4.50?

 

Personally, I'd go wider to start with. Why go up in diameter, yet no wider in width, over a stock 16" x 8"?

But I digress......

If you like the FWD-looking offset of Vette & 4th gen wheels? Go with 4.75".

If you prefer the deeper dishes like a real RWD car should (IMHO) have...Go with the 4.5".

Which wheels you looking at?

 

we are talking about a while 1/4" here, they will both look fine. 4.5 will put the wheels out the exta 1/4" and put them in, IMHO, the ideal spot.

 

I'm looking at the Torq Thrust II's or the M's.

 

How about a 17X8 with 4.50 BS and 0mm offset with the same 245/45/17 tires? I love the look of these rims! I think they will have a nice deep dish look. This is a Torq thrust "M"

 

Nice choice.

I still say go 9" though & get 275s.

 

275's front and back? Wouldn't a tire that big rub in the front? I think the cost of a tire that big scares me also. LOL

 

When I first put my 17" x 9", 0 bs ROH Synpers all around on my 87 GTA....I had 275s up front, 285s back & nothing rubbed.

Now I'm very lowered (adjustable height, so no fixed 1.5"/2"/2.5"....whatever) & still don't rub the wheels.

 

With the 4.5BS the wheels would still be inside the wheel well right? I mean they wouldn't be sticking out past the lip at the top correct? I'm gonna price the 275's and may go up to the 9in wide. I'm going with the "M" for sure though.

 

I'm going to stick with the 17X8's with the 4.5 back spacing. What about going to a 255/45/17 instead of a 245? Would that work on the car and with an 8in wide wheel?

 

Sure. People commonly go from the stock 245 to a 255 on the stock 8" wheels.

 

yes, a 8" wheel will not be outside the fender lips at that width. If you go 9", the BS needs to be adjusted

 

Thanks for your help guys! Can't wait to get them on the car!
