The Progress Group
Antiroll bar/lowering spring comboProgress has developed new front and rear antiroll bars and sport lowering springs for the all-new '03-'08 350Z. The antiroll bars are 33mm solid steel in the front and 22mm solid steel in the rear. Both of these sway bars have three holes of adjustably. The bars are designed for use with the OEM endlinks. This new antiroll bar system will improve steering response and minimize body roll while cornering. Combine the antiroll bar package with the all-new 350Z sport lowering springs and the rear-wheel-drive Nissan becomes an entirely new beast. The springs are cold wound, shot-peened, load tested, and include a lifetime warranty.
MSRP: $239 (springs), $189 (sway bar)
