For those of you who would like to dig at the track, keeping a flat footprint is key. If your front is lifting, your geometry is changing. Here's how to stop it.

Get two center rear seat belts, some scissors and a lighter. Shorten them like in the picture:

Get a hacksaw/whizzwheel and cut off the part in the red circle:

Take the non-buckel end you just cut and slip it over the rear stud on your shockhat:

Now bolt the buckel to the back of the lower fork:

If you're a dumb riceboy and somehow mount these so they fray, tear, wrap around your axel, and send you into the wall, I take no responsibility. But if you bolt these on and get three tenths for $5, like I did, you're welcome...

I could see that working great. But if you had one of those 1 in a million things where it locked up an axle and shot you into a wall at 110+ it may hurt a little.......

At full extension set your camber to 0 degrees for maximum hook.

you can buy brand new lap belts for $10 in most parts stores and they come with new mounting hardware and choise of color. ;D

Some of auto-x guys use chains on their camaros and mustangs. :somb:

meaning, measure how much the front end lifts up at launch and then make sure camber is set to exactly 0 at that point?

Or put the straps on, jack the car up so it is hanging on the straps, set to 0

so do you want to adjust these so there is a little lift allowed or do you want them tight when the car is resting on it's own weight?

Play with them. My best pass had a bit of slack. After that I added tension so it wouldn't lift at all. I think the whole package is what you're after... these are just a variable. If you have a solid rear suspension I'd say you'd want some slack. If you have some squat in the back you could probably run them with tension at ride height.

Think about the bushing deflection under power, hanging is for bad nignogs.

i picked up an extra spare to run with mine for skinnies in the rear this year

excellent write up. love the dot leagal

crttaz · « **Reply #20 on:** March 19, 2009, 04:53:52 PM »

not very safe since spares are only rated for 55 mph.

155/80/13's @ 60 psi, just remember to air them down before driving home unless you want some scary drift action.

my track is 1/8th mile and i will change them when i get there

Seatbelts are also very useful for engine swaps. Great idea

I wish a dragstrip was closer to my house...sigh

going to get some anyways even though using it during aformentioned engine swaps will most likely where they see action

We have three in the area.

I was see Fowee run at Thronhill, a redneck track
