Mazdaspeed 6 wheels?
 

Thoughts on getting these? Looking for decent track day wheels... I been using the S1 18’s.

The Mazdaspeed wheel specs are;

18x7.5", et 52.5mm. 5x114.3 with a 67.1 hub bore. T

16.9lb each.

Is this a upgrade? Seller wants $800 for them, not in great cosmetic shape but will work for racing.

Thoughts? Thanks,

$800 seems a little high for used, narrower wheels when there are several options from TireRack in 17x9 and 18x9 for less.

Were the MS6 wheels 18x7.5? My MS6 wheels were 18x7 +55mm. Do you have a link to the wheels? These would not be an improvement, If you went with 17x8.5 - 17x9, those would be a good improvement.

Yes 18x7.5, ad below.

I also had a chance to buy the mazdaspeed rx8 wheels but seller wanted $$$$ for that which I didnt think made sense... are those good for track or also too narrow?

It's not that they're too narrow. Hell, you could run on 6" wide wheels if you wanted. They'll work fine but there are better choices.

Thoughts on the R3 wheels which I think are 19x8? Are they better track wheels than the stock S1 18x8 wheel?

Define better. What are your goals, here?

Weigh the same but 1" larger in diameter so angular momentum will be higher (they will "feel" heavier).
19" rubber will be more expensive.
Good wheels overall but your goals will dictate whether they're a good choice for you.

For the same or lower price, you can get Enkei RPF1 in 17x9 which will be muuuuuuch lighter, have lower angular momentum, wider, and you'll be able to use cheaper rubber.
For even less than that you can get the TR Motorsport C4 in 17x9 (lighter than R3 wheels but heavier than the RPF1).

Thanks bud, appreciate all the input.
