I plan to upgrade the 27 car and still run in AI, but there is no way It will be in the true "spirit" of AI or near National level. Any 3rd gens in AI?
Things I have:
Motor (@360 RWHP) -
Plenty of HP, you might want to tone it down some and run lighter. My little 305 doesn't make that much. :lol:
richmond 5 speed (heavy mf'er) -
That should be sweet. I wish I had the coin for one. I finally got my 4 speed working well and it's not broke, so it'll probably stay a while.
Things I must do:
rebuild diff and get rid of 4.11 gear -
I run a 3.64, and I'm probably going to put together another center with a 3.3x or 3.4x for big tracks (Road America, Mid-O, etc.)
do something with current unreliable brake setup
Wilwood FSL 4-piston calipers with 1 5/8" pistons and C6 base rotors. www.flynbye.com for the brake brackets. You'll have to speed back up to make it to the corner the first time you use them. I told a TT'er about them earlier in the season and he raved about them at the last event this year when he got them on the car.
Things I can do:
find weight savings (currently 3,380 with 175 driver)
Get rid of everything that doesn't make it go, stop, or turn. My car can weigh as little as 2920 post race with 225lb driver and 5-6 gallons in the cell. Only composite is the fiberglass hood and it's all still factory glass. There's still ~100lbs I can remove if I want to get crazy.
build splitter
If you think you need it. I don't with a spoiler.
build spoiler (wing is too expensive)
Cheaper to buy one unless you already have lexan laying around. Buy a spoiler for a dirt Late Model and trim 6" off each side. I got mine from Speedway Motors for ~$100.
Things I can't afford:
K-Member
Don't need one. Expensive and fragile.
coilovers
Don't need 'em. Not enough tire clearance up front and not enough room to fit them in the back. They want to hit the axle tubes at full compression unless you make a really long shock mount, then you'll have to make new sway bar frame brackets. Might fit with small-body Penskes and 2.25" springs, but wasn't worth it to me to spend the money to try.
shock package
Have Koni Yellows re-valved for your spring rate in the front. Koni makes a circle track shock that works awesome in the back. Maximum motorsports charges the Mustang guys a lot for them. ;) I've picked up two sets on ebay for $120/pair.
big brakes
Already told you how above. Don't mess with the rears unless it's to go lighter. '89-'97 PBR brakes work great.
bigger tire/rim package for bigger brakes
C5 Z06 front wheels are the lightest factory wheels, 19lbs. I put 2 sets together for $400/set a couple years ago.
