I raced Regionally this weekend. I did not go to KC for the 2 day event because of the forecast of rain. The local course was small with one straight at the beginning and the end which didn't compliment the Fit whatsoever. I would guess I lost 3-4 seconds out of staying competitive in PAX because of this. The Avon Tech RAs stuck to the pavement nicely. They're a little on the heavy side for R comps IMO which did affect acceleration. The Fit handled quite well regardless with a lot less bodyroll than you would think. I won my class against only one other car...a '90 Celica GT on Victoracers.
I had a lot of problems with the manual sportshifting. I haven't looked into it much yet, but it seems it wants to upshift in some situations (maybe if you hit the rev limiter a couple times???).
Is the Fit the car to have in HS? No, but I'm sure most people could still win Regionally and have fun doing so. I truly wish there was a more powerful version available. Even 20-30 hp would make this a different car. Maybe a Fit Si or Type R??? :P
I had a good time. Driving the car was so easy. It really goes where you point it. The balance of the car is front heavy...so much to the point you don't even seem to use the back tires much. This is probably due to the fact the gas tank is mounted under the front seats. It lacks the power to really get you in trouble too much. I tried my best to throw it around like I've done with previous cars I've raced and couldn't get it out of whack. Even so it drives great on course and doesn't feel like it's understeering to the point it's not fun.
Upgrades:
K&N panel filter
CG Lock (best $35 I've spent on AutoX)
205/50/15 Avon Tech RAs wrapped around 15x6 OEM Fit Sport wheels
Final thoughts...this car needs lighter wheels and tires. I don't know what other race tires weigh, but I weighed the Avon Techs at 23 lbs each. There aren't many choices to run lighter aftermarket wheels due to the Fit Sport's high 55mm offset. Keep in mind the R comps run wide and slightly rubbed the rear shock dust boots. I would recommend to run at least a 3mm spacer.
I'm not sure if I'll run this car again. I'm on the fence about it. The lack of acceleration was a bit dissapointing for someone who's starting his 8th season of Solo. I'm sure there are other courses that would compliment the car more, but the one I ran wasn't one of them. Don't let that shy you away from racing your Fit. You'll have fun! Just remember to keep your expectations low if you're used to much faster cars.
Now for some pics and vids...
Ready for action
I messed with tire pressures all day and couldn't get the rears some work

At least my passenger seems to like it. LOL
