This isn't a question about aesthetics, but functionality for road racing. Specifically, does the stock undertray attach in any way to the GTC front bumper (real or imitation)? I ask because I want to be able to fully seal the area around the radiator for proper air flow during road and track events. Additionally, are there ducts for the oil coolers that force the air to the coolers?

thanks,

Ramon

 

I am making an aluminum undertray, that comes out past the front of the GTC splitter, both increasing its(the splitter) size, and reinforcing the fiberglass. The GTC side vents function well for two large oil coolers. Mine is a Rotary Extreme 2nd gen version, but design is very similar. Carl

 

No, the stock plastic undertray would not attach to the GT-C bumper. You might want to ask Jason @ jt-imports if they sell one, otherwise it looks like you'll have to fab one like Carl OR pay $1700 for the MS spec R undertray and pray it fits

 

Thanks guys. I guess this rules out the GTC for me. Plan B = Pettit's replica for the 99spec.
