1. Call your tuner about your WHP goal and take his advice 100% without listening to us.
2. You have no idea about suspension. Get that through your head first off. I know it sounds harsh, but lowering with coilovers and using swaybars to "stiffen up" is what ignorant people do. Visit www.turninconcepts.com
and click on their contact us section where their phone number is. Call them on Tuesday. Tell them your budget and goals and buy EXACTLY what they say with zero thought on your part. If you do anything other than what I have just said you will be super unhappy and your car will bounce around like a log wagon with no load. If you buy exactly what they say, you will be super happy. This might be my best post ever.
