I have driven my RS at least 2,000 of its total 10,500 miles on the racetrack. I have been to every road course in California (7 tracks) and one in Nevada in the 4 months I have had the car.

Up 'til now, I thought it was bullet proof. It is built like a tank and nothing ever breaks at the track.

But last weekend at Big Willow, I started to feel a slight "grind" on the 4th to 5th upshift, as if my 5th gear synchro is starting to wear out. If I make absolutley sure the clutch is all the way in and make a sort of deliberate hesitation between the 4th and 5th gates, it doesn't happen. I was really only noticing it on the long front straight, where I was revving very high and rowing through the gears quickly.

I have only felt it once on the freeway and never on the street. Does anyone else have this problem?

I get the 5th gear grind if I skip gears, but not from a 4th to 5th shift...... but I am not at high RPM when I do a 4th to 5th since I don't do open track racing. I think skipping gears puts more strain the the syncros, but after enough small strains the same damage will be done as a small amount of large strain events. Mitsubishi's seem to always have synocro issues.

Later,

Keith

Yeah, stock clutch. It seems to be able to handle the extra power. I probably have about 100 crank hp more than stock.

grind in 5

there is a tech bulletin on the 2-3 upshift and the 4-5 upshift. if your car does this there are new and improved synchro's for it and the dealer will install for free
