hi paul,i have an issue i hope you can help with,when reassembling my car (t4)and setting it all up,i found that the front right shock needs 1 whole turn more on the collar than the left yet the rears are exactly the same amount of turns to get the ride hieght right,an ideas why this might be,ive looked all over and cant find anything wrong with the shocks or the chassis?shocks are all equal lengths

First check the balance to make sure that the chassis is balanced left and right.
Second i would crack the shock towers loose and be aware of the effects that torquing all 4 screws "same direction" could have (I could easily make the shock tower sit .2mms off level if i don"t tighten it properly), if you want to go crazy with this you could set the chassis on the table and measure with the back of your calipers pit board to each ear of the tower, but again I wouldnt go to crazy.
Third i would make sure your shocks have fairly euqal drag on the seal, if a seal has a lot more drag it could keep the car down .1 or .2mms easily after squatting it on the board. this is even more common with the softer spring set ups.
Possibly replace all your suspension mount screws (long ones), and check for slight bend in the sus mount also.
Lastly I would loosen up all the screws and re set all the bulkheads and not over tighten anything and check again.
All this being said, your main concern is that the tweak and cross weights is proper. I would rather race a car which that is proper and sits .4mms low on one side than race a car that is perfect flat but tweaked.
Hope this helps. Thanks!

Hi. First i want to say that it is worth looking at but if you look threw all the major things that could cause it and it still sits a bit off, I wouldn't worry about it. I rarely race a car that is perfectly flat. allowable tolerance for me is .2mm's. Here are some things that i would check, no real order of importance here.
First check the balance to make sure that the chassis is balanced left and right.
Second i would crack the shock towers loose and be aware of the effects that torquing all 4 screws "same direction" could have (I could easily make the shock tower sit .2mms off level if i don"t tighten it properly), if you want to go crazy with this you could set the chassis on the table and measure with the back of your calipers pit board to each ear of the tower, but again I wouldnt go to crazy.

Paul,
I have been thinking about this for awhile now and have been curious. Have you ever thought about putting on a one day seminar about chassis set up and how to drive a better line when racing with others? These types of seminars happen all the time with full scale racing and thought a great professional like yourself could benefit from it.

I'm looking around at the different options for 1/12th tires for the IIC. How have the Gravity 1/12th tires been working at events like this? Which compounds would be the right ones to get for 13.5? Are they off-set like Jaco rims, CRC, or something else entirely?
Thanks
Thanks

OK Paulie . I'm back , BTW the rear toe ony usgt car was the issue with tires .. Tks for ur info
Now to my most recent findings . this problem is with my 17.5tc .
Clean tires with 2 runs on them even wear on all 4. Dopeing them 5min before run with STX.
Burnout as it hits the track , run 2 warmup laps to get some heat in the tires . 1min pause till we get to run (sometimes more) 2nd lap in car feels great , as i expect it to feel anyways .
10laps in car begins to push and doesnt rotate as smooth thru the turn (as if rear traction has doubled) . seems to stay this way all the way till end . I've temped the tires and they r 105 on outside front (sweeper I'm guessing) and all others r 95 deg . any ideas without going into set up 2 deep? BTW its a T4
