Hi,
1-The 2mm on top arm means the upper arm is shimmed 2mm to get a longer upper arm.
2- the reason why I run the stock spec is more of a feel thing, I like the feeling of it on the down side is you dont have much setup window since we pretty much can only run it on one. I ran stock spec with 4.0 STD wind with 12.5 works rotor correct.
3- if I was to go run at Norcal, I would start with the same setup with lighter oil on side and center, probably 20 side and 25 center and would use a blue center spring and green side ! thats about it I think.

I'm just trying to talk to a driver that used same esc for 12th mod and 12th 13.5/17.5 as to not have to have two cars or two speedos
In getting back into 12th and my last item to buy is a speedo and I'm just thinking ahead if I go to big race and I want to race mod and .5 class
This is just an speedo question not about tires or anything else that might change from class to class
Do you remember any LRP top racers that we're competative with same speedo in mod and .5 classes?
Thanks again

Have some problems with my TC6 on a mid-high traction carpet. On two places it's bumpy. At the entry of corners I have lack of steering and at the exit chassis roll (car flips when throttle applied) I was running a 13.5T motor and Levanens set-up from Warsaw only the ride height was 5,5mm front 6,0mm rear because otherwise the car bottom's out. When I add some steering the car had even more tendency to flip bit the steering at the entry was better.
It would be nice to know in witch direction to work ...
Thanks for help, Lojz

Lately I have been running my shock cap std not drill. the main difference when I drilled the cap was that it was easier to build a dead shock with no rebound. Lately I have been running about 25% rebound pretty much everywhere.

Keven: I am running one of your older set ups on my car with some changes, #1 roll centers in hole B all the way around (no anti-dive in front), short link in rear, long in the front, reflex 12.5 springs in rear & 13.5 in front, same oil & pistons as u, with shock caps drilled, black sway bars f & r, spool in front, gear diff in rear w/ 1,000 wt (spec r), about 2mm of up travel front & rear, 4 degree C-hubs w/ flipped spindles, spaced the wheels out a bit with spacers on the axles. Running the P37r lightweight body. 2 degrees camber f & r. I am running a fairly high drag brake as well. Running 17.5 no boost on a med to higher bite carpet track with some bumps.
Now, my question. The car has a high speed push and is difficult to drive from point to point, it feels like the car is taking too long to recover from turn to turn, which can get the car "snappy" with the tail stepping out. I noticed your iic set up has higher roll centers and stiffer springs, is that your new starting point or was the traction different than the norm? Any help is appreciated. Thx!

Hi, the main thing I would do is try to lower the ride height. A car that bottom out is not always a bad thing, sometimes it can help handling. The other thing I would try is reducing the droop ! going to around 1.5mm uptravel all around. If that is not enough, the other thing I would try is moving your front and rear shock in on the tower 1 hole and see what that does. Hope this helps Keep me posted on if it helped any, if not we will go some other route !
Before this changes the car was really uncomfortable and hardly controllable now I can push it without being nervous all the time to flip it. Best time 0.4s faster than the last time.
I have another question regarding Tyre preparation. We are using the LRP CPX carpet tires. They seem to work best after 3-4 runs. When I go to a race I have only one run before the qualifying start. OK I don't use a brand new tire for the race but nevertheless it seems like the tire needs to get soaked with tire additive to some point so it can get to its potential. Should I try to heat them for the first run? Do you have any suggestions on how to prepare tires (new or used) for the carpet.
Thanks, Lojz

Sorry about the late reply, I think your setup could use a stiffer spring. I have been running a little stiffer lately for that reason, I think running stiffer will help change direction quicker and also finishes the turn better. When running to soft the car usualy drag the nose and pick up a push. First thing I would do is go to let say 16.5 front and 15.5 rear and see how it goes from there.
I am known to use a lot of push brake more than many drivers but I think this is more of a driving style, I usualy shoot from point to point but then again I am not sure if this is the best way but it is how I have been driving for quite some time so it is hard to change driving style ! I think drag brake is really up to drivers preference, I like to use a little bit but one thing you have to be carefull with is that sometimes people use drag brake as a setup patch when the car does not get in the corner people use drag brake but I like to play with the car first and than as a last resource I will use drag brake.On asphalt I try to not use as much drag brake to not overheat the front tires tho.
Hope this helps.
Just lowering the ride height made a huge difference! I set front 5,2mm rear 5,2mm and the car didn't flip any more. I drove down stops front 7 rear 6. How do you set and measure up travel? With shock length?? I also tried one whole in on both shocks this gave a little more smooth feeling which was good. Using silver springs front and rear, pistons 1;1;1,5 shock oil front 50wt rear 35wt.

Hello Kevin.
I must believe that most of your posted setups are after the mains or are the heats that you ran the quickest and most laps.
I have struggled in the past as traction starts to build throughout the day.
So,I am curious...
After you arrive at a track and tune your car to your liking...as traction is coming up during the heats, what are the common adjustments you make to stay competitive and improve the car with the additional traction?
Thanks,
Jon
