very nice, with lot's of "go fast" stuff. GLWS

MJR911

Nice car, especially the gearbox

KaiB

How can a car run PCA stock or prepared with a close ratio (non-factory ratio) gearbox?

Mark in Baltimore

Are bump steer kits legal in F class?

Astroman

That is a Prepared F car so bump steer kits are allowed.

And I'm sure Doug was referring to the allowed R&P change instead of "short ratios." This is a very well known car in the Southeast.

analogmike

GT Racing 2nd, 3rd, 4th, 5th gears, I guess they could be stock ratios?

Mark in Baltimore

Okay, thanks, Jack.

Option 491

Lots of interest - yes the gear box is legal, as a prepared car you can run shorter ring and pinion. Creates higher heat therefore put GT racing gears and stainless steal sync for reliability. This car runs up front and routinely get checked post race and passes.
