$600-$700 to spend on suspension

[ranisron]

To sum up...

Option 1: Save up for coilovers. You have $700 already, it won't be too far till you hit the 900 magic mark for a decent set of coilovers. Megan, KSport will do the job just fine. Unless you want go higher quality coilovers, i.e. KTS, Silkroads

Option 2: Replace your worn out suspension components. AGX + Prokit = good option; AGX + Sportline = Not so good since ride is too low for the shitty spring rate; Personally my car used to have KYB GR2 with sportline, ride sucked; you will definitely need better shocks than GR2.

Believe it or not, Megan Racing springs have some tough spring rate comparing other manufacturers, and then come in VERY cheap for their spring rate (for example, RS-R Race springs are in the ball park of $200, and you get somewhere around 4.5kg), Megan Racing springs are rated at 350 lb and 275 lbs IIRC, which is in the sweet zone for AGX. Megan springs costs like $100 bucks shipped.
