Cheap ways to reduce unsprung weight?

[tk-421]

What's a cost effective wheel/tire set that would make a big difference in unsprung weight vs OEM (i.e. bottlecaps)?

Add some dunlop dizezza star specs and you'll be very happy. The Dunlops are fairly cheap and incredibly grippy. Drive the hell out of my car even in the rain, and I have yet to even get the back end to feel light.

Nice to see people on R3V that value performance over "fitment".
-I am not a fan of cross-drilled rotors, but they should provide a slight decrease in mass.
-Run a smaller tire size

BBK should help if your financially inclined. Those aluminum calipers are pretty darn light. e30 m3 aluminum control arms. Running coilovers with shortened strut tube and shorter stuts. Although if your already running bilstein sports they are inverted. Inverted rear shocks are good. ABS delete so you can get rid of the reference sensors and rings.

I'm super cheap so i got some drag dr46s. Paid around $712 shipped with dunlop direzzas mounted and balanced and hub rings from discount tire direct. Then i received a $70 visa card.

direzzas are such good bang for buck.
