I am looking to put on fifteen52 17x8 Tarmacs and they only come with a offset of 45. from what ive read so far some people are saying the cars are built for a offset of 50? but yet the stock offset is 36. Would the 17x8 with the 45 offset work on a FD Rx-7?

17x8 +45 will fit within the front and rear fenders. Are they available slightly wider such as 8.5? 8.5" all around would allow you to easy run 255's at each corner without any issues.

 

They make an 18x8.5+45 but no 17x8.5 I was looking at the spreadsheet that was on another form and it said the 17x8/8.5 where the best for the car but they only make the 17x8

 

My 99 Spec OEM "RS" wheels are staggered 17x8 and 17 x 8.5. to accommodate 17X235X45 front and 17 x 255 x 40 rears.





225 front 245 rear in picture.

 

Stock wheel size on S6 FD was 16x8 +50.
+45 should work on 17x8 with 245's. I run 17x9 +48 with 255/40's all around. No rolling, coilovers set to maybe an inch lower than stock with no rubbing.

Center bore size on the FD is 67.1. Most aftermarkets will be larger so you will likely need hubcentric rings to avoid vibration/flexing. I recommend aluminum.
