I would like to get an opinion re two setups for my car that I want to use for autocross(with stickier 245/255 -40-17 tyres)
1.Enkei 17x9 RPF-1 with RX 8 Brakes as a BBK(since the BB kits for the MX5 do not fit this wheel,which is disappointing since I really like this wheel..+saving 5-6 lbs per corner would have been perfect!)
2. 6ULR 17x9 with one of the BB kits on your site
My issue is with unsprung weight as with the first options whatever I gain by lighter wheels are off set by the heavier brakes..
With the second option the brakes are lighter but the wheels are heavier..all though the second option will still let me shed 1 lb per corner if my math is correct...but more rotational mass per wheel.
In your estimation which is the better way to go for a supercharged NC for autocross
