So I could run RX-8 brakes(calipers and rotors) then as a low cost step before upgrading to a Racing Brake type setup. Does anyone know if there are any issues running front RX-8 brakes(calipers and rotors) with 17x9ET52 949 6ULR wheels?
Yes, RX8 brakes discussed here in other threads many times. The only downside is weight. If you need the extra thermal capacity then the RX8 brakes are a cheap way to get it. The downside is that the result is the same as if you bolted up some overweight 25 pound wheels....because those brakes are adding significant unsprung weight at each corner.
Understood regarding the weight... It's just a temporary fix until i have enough for the BBK. I was mainly asking about fitment vs. the 17x9ET52 6ULRs. Sounds like they will fit but will be heavy. Thanks Brian for your insight into the Miata vs. RX-8 brake questions.
