I was wondering if there are any other full suspension kit options other than the Tokico HP kit, preferably one that has some level of adjustment or that is more of a performance racing kit that doesn't require welding. I don't have access to a welder, and it pains me to think about having to pay someone to install something on my car.

Welcome to ZDriver!

The only adjustable route would be coil overs, and none are "buy and drop in".

Actually there are buy and drop ins - Modern Motorsports but the guy is sketchy when it comes to getting your parts - great stuff cruddy service. Tech Toy Tuning now has a coil over as well for the S130.

Thanks! The Tech toy kit looks really sweet, just need to get some more money now. haha.
