Here are some pics of my chassis from the side. Pic 1 shows it flat on its side. Now pic 2 shows it when I push down on the rear left of the chassis (right behind the battery brace). The pictures aren't the best, but you can see the chassis rise a bit. And I've been trying every which way to tighten down the chassis and upper deck screws. I'll have to see if CA'ing the shock towers and motor cutout does anything (only did the outer chassis).

Anybody having trouble with their chassis tweaking? I saw one on the weekend where you could badly tweak the rear wheels by twisting the car in your hands. Tried loosening the screws, tightening them in the right order etc.

Hi Jeff,

Would you believe that I was there last saturday, and forgot to ask who you were!

Not a problem, I'll be there on saturday, bright and early. I should be running Sportsman, I got whipped pretty good in 19turn last weekend.

SoCal setup:
Fr:
50 wt
#3 piston
stock shock positions
Droop: 4
I took away a 1mm spacer from the camber links, to raise the roll center

RR:
50 wt
#3 piston
Droop: 5
Stock shock positions
I lowered the roll center by adding a .5mm shim to the camber links

Misc:
Sorex 36R w/ yokomo medium thin inserts
camber: -1 all around
0 toe

The car was awesome in practice, but during the main, the rear started to break traction. I think it was the tires though, and I'll be trying some 32's instead. I'm going to play around with the setup some more tommorrow night, so i'll let ya know how it works...

Try this dreambrother:

Loosen ALL the top deck screws, including the two in front of the shock towers. Put your racing batteries in, and secure down with the battery brace or tape. Then tighten...see if that makes a difference. I don't think it'll be ABSOLUTELY perfect, cause mine isn't.

Thanks for getting back. I was pitting near Jose last weekend. I ran sportsman stock....white/blue vauxhall vectra

I think I've been chassing setups using the same sorex 32/green inserts that I've been running for the past 2 months. This weekend I'm going to try 36's with thin inserts and some CS32s (any luck with the takeoffs?).

Basically....I run

Front: #2 piston 40w (losi)
AE Blue springs
roll center: 3.5mm
camberlinks in stock position
NO swaybar

Rear: #2 piston 40w (losi)
running slight anti squat.....5mm shim on the F block
AE silver springs
roll center 2.5mm
shocks...all the way out on top/bottom mounts
camber links: all the way out on both inside and outside mounting positions.

I'm going to try a 2.5 rear block to take some toe out. I know it's not much but we'll see. I'm also going to switch to 50w oil all the way around

Hi Proteus,

I DID see your car run, it looked really good.

Your setup looks good, i'll give it a try tommorrow... I'm going to try some old tc3 setups i have, to help get a starting point.

Which reminds me: WHY isn't there an editable Pro4 setup sheet????

As far as the tires: I've had really good luck with 32's and thin inserts, the greens tend to overheat the tire and make it slippery later in the run. I haven't tried the take-offs, but some say that the Yokomo 139's hook up ok.

SoCal can really change rapidly, the traction can be great during open practice, but once the temps drop, everything gets slippery.
