You have to group things like....
Stage 1. Wheel and tire package.
Stage 2. Suspension.. Koni's/H&R/Eibach's/GC's/Rear Sway/Front Tower, sub frame connectors
Stage 3. Exhaust.. Headers,Bassani,Borla,KKM,K&N,Sho Shop y-pipe
Stage 4. Trans... Quafie, Upgraded clutch, etc.
There is so much to do. Just set a plan for you car and try to put everything in to groups and get the groups installed at the same to get the most impact.
