I am running s Spit6 in SCCA solo (autocross). I have not been able to determine which class I should run in, other then Heritage.

If anyone else is running a Spit6, what class do you run?

Wow, no idea what class a 6 cylinder Spit would go to. My 1500 is in FSP. You'll probably have to get a ruling from the club.

How does the car handle on an Autocross course? I've ridden in a couple and am always surprised that the power keeps rolling when I think it's going to stop. Haven't driven one, so don't know if the extra weight on the nose hurts very much. There are times when I think a little extra weight wouldn't hurt that much.

It handles very well, but I have only run twice and it is the only one I have autocrosseded with.

She started out as a GT6, so the transplant was the body, rather than the engine, does that make a difference?

My friends are now running Heritage with Spits. Just another stupid ruling SCCA has come up with to level the playing field. They are good at that,believe me. If there are not enough Heritage cars at an event you run your Street prep class. A rule,within a rule. I started running my TR4 this way in 1978. I soon tired of all their rules even back then. Rules encourage one thing,cheating! Then more rules are heaped on to stop cheating. It's always been a viscious cycle with them.



Sometimes you succeed,other times you learn.

The Spitfire body is lighter, so that would make for a potential performance advantage over standard GT6.

I am having a bit of an issue with it going nose down in the corners, so am I going to try stiffening the front end some this winter.

Yeah, takes standard coilover springs, widely available from many vendors, just need to choose the right rate and free length to get the ride height you want.
Mind the alignment after fitting springs.
If this is a daily driver, you can choose to promote tire life, or if a dedicated autoX, can use some extreme settings to gain performance, at cost of tire longevity.
