Hi Guys, i have done it 100 different ways, i do it by hand and get it pretty close like that, but i tweak station (bubble) will do the same thing as feeling for the weight like i do. If i ever have a car that is seriously awesome i will put it on 4 scales to document the F/R weight %.
I have also used 4scales to tweak the car and it does work for me, youl never get it totally perfect, but you just want your left and right resr close and your left and right front close.
Maybe you are getting varied results from variables with the 4 scale system, next time you try this first use the tweak station get the bubble centered, then put the car on the scales, wright down the weights LR,RF and so on. then leave the scales in the same spot but rotate the car so the rear tires are now on the scales that the front tires were on. then compair the results. if the results are way off you will know that your scale system is flawed. tweak in the board, not accurate scales, different height scales, etc.

(1) Please define "close". Is it 1%, 10%, or what?
For example, if you have 350gms per scale (4 scales), that would be 3.5gms and 35gms respectively.
(2) Do you try to adjust for the cross tweak (ie: LeftFront+Right Rear, versus RightFront+LeftRear) as opposed to just the rear, and just the front. If so, do you shift the electronics on the car, or add weights, or what?
Cheers

Thanks Paul, if you do see your car isn't centered on the tweak station where do you start in order to correct the problem?
I also noticed I built my car and ran it last weekend for the first time. I noticed after a couple of runs my body started dragging. I trimmed it on the sides thinking this is what was dragging. Next time out, it was still dragging I trimmed the front and that fixed the dragging. When I got back home I was checking everything and noticed my ride height had dropped from 5.0 for 4.4 letting me know why the body was dragging but I never thought to check it since we're running carpet and tire wear is really minimal. With this being said I assume my shocks settled in? Is this normal? This is where I plan to start on getting the tweak set back on the car, because I know everything is built equal from the left to the right side.

hey Paul
i would like a to get back into sedan racing after a 5 year absense. I was going to MMI at the same time you were. We met a couple times and raced against eachother at SRS. after leaving AZ i moved somewhere that didnt support sedan racing, i.e. no tracks. I just want to know if sedan racing is still popular on the club level at all. the class has appeared to have completely faded away at the amatuer level. I'm moving to denver CO and would like to know if sedan racing would be the right choice. is it dead? i ask you because you get to travel all over the places and probaly have ur finger on the pulse of sedan racing in this country. thanks.

Paul-
What;s the theory behind setting the front hinge pin holders with 2.25mm shimming? This effectively makes the front track width wider than the rear yes? What's the benefit? I see more and more people running it this way.
Also, what are your thoughts on diff height with rubber tires?
Coming back out to timezone anytime before the carpet nats?

Hi Peter, yes i normally use the 2.25 behind the front pins. I started doing that a couple of years ago just to make the front end more predictible. it does take away a little steering but i feel like the stability that you gain is well worth it.
As for diff height i feel like the higher the diff the more traction the car has, i never run them low, normally i use standard high all the way around and just leave it their.
I felt like my car was really good at cleveland, i will have that set up on the xray site soon.

I know this has been asked before but;
How does raising the the camber link an even amount at both ends (so the angle doesn't change) effect the handling. i.e. when using the H1 H2 QRC's it mentioned that another 1mm must be added to the outside to keep the link the same.
Thanks

Paul,
When you use the shock collars to adjust fr tweak, do you adjust the collar on the opposite side and opposite end of the car? For example, if the car has too much weight on the RR you reduce the preload on the LF and increase it on the RF to make sure the ride height stays the same on the front of the car?
Also, when lifting the car to check tweak, do you use the tires on the car to look for differences in how fast each side lifts or do you use setup wheels?
Thanks

Hi Paul, couple of questions on the t3 11 running the car with l1 and l2 and then changing the whole car to h1 and h2 what effect would this have on the car?
also on carpet running rubbers running the gear diff I find very snappy, do you run this?
Thanks

I tewak my cars with tires on it, i will spin the tires to make sure im not on a high spot and take the average if it is. i look first to see if the suspension topps out fairly equal, then i will look to see if the tires are coming off of the table at the same time.
Yes the gear diff on carpet can be very hard to drive. try going thicker diff oil, i thought that 2000 was easier to drive than 1000 for sure.
Thanks!

I am guessing since you are making the rounds to all the big races using sticky fingers and jack, instances where the cars always seem to be more edgy, 2.25 is nice and easy to drive. I will for sure give it another try the next time I head to Timezone.
Later!
