Zero2Sixty

I want to lower the car, replace the stock shocks (decarb's) and increase street performance as its not all about light to light runs.

Help me out here, I have read lots of posts and there are many different options & products (street vs track etc..) so please comment on what I've chosen so far. This would be used strictly for street-use.

1. Ground-Control coil over kit with Eibach springs (spring rate based on street-use only), matched with Bilstein HD's. This is at a higher cost but with adjustability.

or simply

2. Eibach Pro-kit with the Bilstein HD's. Obviously this the lower cost alternative.

I've already ordered Relocation Brackets, Lower Control Arms, Adjustable Panhard Rod.

Thanks in advance !
