I have a 100% stock 2008 Nissan 350Z, My Hotchkis Front & Rear sway bars just arrived. Debating on Tein Basic Coilovers or Eibach Pro Kit lowering springs.

I only drive the car on the weekends, I plan on doing maybe 8-12 track days a year and car is stored in my winter months. Just looking for better handling on the street and the track.

What are the pro's and con's?

Thanks

 

Better handling you want for track days.

Return everything you bought
Buy 18x10 or 18x10.5 front and rear.
Buy 275/35-18 front and rear
Buy front adjustable upper control arms
Align to -2 rear camber and -2.5 front camber

Hit the track and know you have better suspension than 90% of the people on this site.
