SL55/63/65/R230 AMG: Stealth mods to 2009 SL63
I'm trading my "07 SL 600 Renntech on a 1000 mile SL63. I'm interested in go-faster mods, but this time, they need to be stealth, to avoid any warranty hassles. I thought that to start, I'd get a limited slip put in. Any thoughts as to brand? Also, are any chips non-detectible?
Thanks,
David
