most bolt-on kits arent worth it. you can spend up to $2500+ on bolt-on and end up with only 25+ in HP increase. That has to be one of the weakest hp/$$$ ratio..

If you want speed, torque and fun, Forced induction is the way to go. Anything else are just for the BLING.

...yeah, what trueplay said. Turbonetice makes a great ST for the Coupe. It's got me putting down 350 rwhp. Not TT stats, but it's just fine for quick accelaration onto the on-ramps!!!
