Alright guys. I have a 2009 CTS on 20s. I want to lower it 1 inch. I got the eibach springs for my car. I have an independent mechanic that's going help me. Are the springs all I need? Do I need new shocks?
CTSmylife2009......YES. Sucks too, but I noticed when I put my aftermarket rims and tires on (20s) my cars acceleration suffered. Also its a little bit louder in the cabin, like theres more road noise. But its totally worth it in my opinion lol.
@CTSismylife2009, any car will feel heavier once you do plus sizes on your wheels- in overall diameter and width...unless the car is turbo-charged...then you just up the boost. On my F350 dually I changed my stock 19's for Alcoa 24's (semi-truck wheels) and she still has plenty of power/torque. On my Supra, I had to add 2-4 lbs of boost to feel the same with the 19's as it did with the stockers (17's), but the 19's are considerably wider (19x10 front and 19x11.5 rear) as opposed to stock. Unfortunately, we cannot change the horsepower in increments of boost in the CTS (non-V), so we are forced to either deal with the lag, or buy light-weight 20"+ wheels (which are hella-expensive).
