2009 Shelby GT 500 upgraded to 600rwhp

I've been helping a friend with his Shelby find traction after he installed a cobra jet intake w/ JLT and tune. The BMR lca's & panhard helped but I believe new struts and shocks are needed as well? He's looking at the newer GT 500's and is tired of building his I believe. Mickey Thompson's help but he knows not to drive those in the rain and is perplexed as he enjoy's light to light street action. What should I do? Now I'm perplexed.:frusty: He uses these Nitto's for now on the street.

What exactly are you looking for? Tire / suspension recommendations? Ways to make more power?

Power to the ground

Thank's yea, suspension. I am trying to help the pony's grip as it spins too much, maybe it's a "Driver Mod" he's my age 55 or so, I'd think he knows how by now. I went for a test hit to watch the gauges and listen and it makes all the right sounds and such. I have recommended Viking rear shocks and Strange 10 ways for the front, but he hasn't responded as of yet. Oh he did American Racing header's with BMRP 3" cat back off road. He has an Eaton supercharger.

Sticky tires are your only hope on a hopped-up GT500 since the LCAs have already been addressed. Shocks will help a bit for weight transfer, but traction increase won't be dramatic without better tires.

Mine was completely tractionless at ~540 to the tire on regular street rubber....
