Stiffer suapension

Don't know you'd probably have to go aftermarket springs? Coil overs come to. Mind I bought set for 300 complete . Bolt on go up and down adj rebound etc pillow ball upper mounts etc . Can be a kidney slamner if ya like

 

Toyota Corolla and Pontiac Matrix have compatible suspension parts like sway bars that are stiffer... As for Springs and Shocks that market is rigged to be ridiculously overpriced with very little improvement gained. Whereas a replacement front sway bar kit for a compatible Corolla is only $100.

Another example is chassis stiffening where they'll charge you $300 for a chunk of pretty metal you bolt to the bottom of the car and you could use just about any chunk of scrap steel for free or cheap to create the same benefit.

More to the point you can learn lots if you use a search engine to read through all the threads on that subject on here... None of us have the time to answer your question as thoroughly as your own search can.

 

300 coilovers do fairly well you can tune the rebound and compression lift n lower car. Different spring rates in the 4 inch springs are cheap too. That's what many are paying for struts sooooo. You couldn't buy the metal collars and the threaded joints and all that to make C O. For 300

 

What are "300 coilovers" ?

Can you please share the name and manufacturer and how much they cost?
