Brakes and suspension, stock is not sufficient for those power levels, no matter what a magazine says, your doubling the stock output and the car will act alot different than stock.
and much more but those are the main things i can think off hand

For what it's worth, I've seen several mkiv tt's making 600rwhp using piggypacks, with extremely stable fuel and timing curves. Imho, a standalone isn't necessary (or cost-justified) until at least 750rwhp+.
Again, a brake/suspension upgrade depends on the application. The oem bakes & suspension roadraces just fine, even with a single turbo. This is a proven combo in One Lap of America, and other roadracing events. My interest here is to provide advice for a cost-effective set of upgrades. Sure you could blow/waste a bunch of hard-earned $$$ on big brakes, penske shocks, sway bars, etc., but is it really necessary? Until I know that he's running (for example) better than 1:40s at Road Atlanta, the oem brakes (with carbotech pads), and oem suspension are JUST FINE. If you don't mind me asking kwnate, please provide some sort of first-hand experience for challenging me on this point. Have you personally roadraced an mkiv tt with the oem suspension?
