I find i like a bunch of oversteer in autocross but on the big track looseness can be hazardous to your health.

I wish I could give you a ride or let you drive it, words don't do justice. I'll make a video of my car after I get it dyno tuned, this week... next week. Have to install my MSD dist and stud girdles but it's raining right now so... If there's anything you want me to do in the video let me know. My only suspension issue right now is that the new motor lightened the front end so much, I have positive camber on my front tires right now. I can feel it around turns.
I need to cut half a coil off this summer.

Try and find some open space like a big parking lot and drive in a circle. Keep pushing it harder and harder until the car slides either front or rear. Please be safe. Don't take chances for the sake of getting a video.
A video would be great. I'm looking for a cheap video camera so i can show you guys some video this summer. My wife won't let me use her's.

Man i had fun today. NHIS with the new 17" wheels and tires. See wheels below. I bought new Sumitomo 275/40/17 tires. They stuck like glue from what i'm used to. I'm ready to ****can my 15" wheels.
Fried both my front wheel bearings but i usually go through a set every couple of years. We only had 1 blown engine and one wheel fell off a Subaru WRX. It was bitter cold and windy and froze my as off all day but it was worth it.
I'm doing ok in the corners but need to get the engine dialed in. It bogs really bad when the secondarys open up to the point where the engine acutally loses power at full tilt for 3 - 5 sec. I need to put the vaccum dashpot back on and maybe try some different secondary metering rods.

Turtlevette,
I'm surprised you're running a vacum secondary carb for road racing. You probably lose alot of time on exit. A good mechanical secondary double pumper will really get the car moving from part throttle apex to the exit.

Yellow 73SB,
If you're asking me, I run 1 1/8" front with 550 springs (one coil cut). For the vintage rules, I have to run a steel spring, so I have a stock 5 leaf with no rear sway bar. Everything else is stock urethane.
Jim
P.S. This is what the '73 looks like now

Lol im going to run ~850 front springs and a 550 rear. I already have the 550 rear I just need to order the fronts. I think I'll need to step down from 1 1/4 fornt bar and 7/8 rear bar.

I removed the vacuum dashpot on the secondary so it was bogging really bad. I'm gonna try getting the Q-jet running good before i resort to an aftermarket carb.
You running 15" tires??

Yellow 73,
Yeowww!! That thing's gonna plow. I don't get much body roll, but the track I normally run (Texas World Speedway in College Station), is pretty uneven, so I need a little spring
Turtlevette,
Yeah, our vintage rules require 15" tires and no lower than 60 profile, so I run the Hoosier 245 street TD's on the front, and Hoosier 26.5x9.0x15 on the rear. About $450 a set, and they last 3-4 weekends (losing about a second a lap each weekend!)

It has a lazy spring.These tires grab pretty good and i was able to create some real seat of the pants Gs in the turns especially the banked one. What bothers me is that it looks like i'm getting positive camber in these picts. I'll have to dial in more initial negative and i think i'm gonna go to solid steel bushings to help. Most of the serious guys in the club dial in so much negative it looks like the wheel is going to fall off.
I'm pumped about how much difference wheels and tires made and thinking towards the future to do fender flares with 17x12 running the 315/35/17 on all 4 corners. The problem is finding wheels that don't need adapters. I would have gone with 10" wide but you can't find them. They would have fit with 5" backspace.
I don't understand why you have no interest in doing track days. Its an adrenelin high like you've never experienced. Don't they have lots of tracks in Germany.
