the bmi db12 was amazing this weekend. The car had a little push in stock, but in mod, there was no-one else's car that looked better on the track. If it wasn't for the driver, the car would have finished with a 2 podium in region 9.

Also tie breakers in triple a mains are a bitch!

who needs a carpet and an asphault chassis.

I haven't rebuilt the front end on this car in over 2 years, springs are definitely getting changed...

I do have almost a 3/4 mm difference in lower arm height while measured on the car off my hudy board.... Hmmmmm.....

0.18 front spring... the other stuff i played around with, hard to make up what's beter.. track changed a lot too...
It might be strange getting advice from the one that placed dead-last in modified, but go for a stiffer center shock spring, and center shock oil.
If your car starts to traction roll on corner entry, coat the front tires outer sidewalls with CA.

Have you check to see if you might have one lower arm might be a stock asoc arm and one might be a crc or irs lowared arm.

If your front end is off from left to right, the first thing to check is the lower arms and screws. If you have a set of lowered arms on the car, they're probably not the same height. I've had to sand them (caveman fix) to get them to be the same height. The other thing to check is the screws. A bent screw is going to hoze the whole front end.

Also, if you're running brushless, the weight of the chassis will probably be off from left to right. My chassis sets almost a half mil off when it's tweaked properly.

They are both stock arms.... This is a recent problem, the car was fine up until this weekend...

Check the lower pivot ball. I bet it's loose and doesn't fit snug.

I had a chassis delaminate, and it was doing the same thing.
Everything looked OK, just when you twisted the chassis, you could see it was coming apart.

Yang, your car was good in Mod, how did you get it dialed on that ice rink? My asphault car was horrible I don't know how the tie-breaker was decided

When I get my carpet chassis, some of us will make a road trip up to Dallas

I've tried more jack the gripper on the front tires, but that made the car roll on corner entry. I've tried to make the center shock harder but that made the car bounce over the bumps.. it was really bumpy

i'm running a crc 3.2R


try a 20 spring on the front. more caster will help the steering from the center off. it may also be possible your rear is too stuck and driving the front.

actually it was the db12 chassis that help most. with so much weight in the rear, it planted the rear out of the corner. and going in the weight transfer was actually a little too much. but I wanted a lot on the rear tires.



come on up. we are night racing the last 2 saturdays in nov. you guys always have a place to stay.

actually, the secret was the car oven. I went to walmart and purchased a cooler bag, just big enough to put our car into. and then I picked up one of those cup heater to keep your coffe cup warm. we would sauce our tires and then put it in to bake. they came out warm and tracktion baked in.

work great for me and tim
