Lower trailing arm question

[keeter57]

when the car is sitting on the ground,at what angle if any should the lower trailing arms be for maximum traction.

In my opinion lowers should be level

The lowers should be at 5* uphill twords the front this will give you the longest duration hook up.
And the least amount of rear steer.
Adding more up hill angle will hook the car up sooner yet it wont dig as long.
Remember the right side is in compression and the left is in extension so rear steer (which isnt a bad thing) will also increase.

All great info. Just keep in mind, the more rear steer you have, the looser the handling will become. Shouldn't be an issue if the rear is in the car correctly, just check your wheelbase. Just a tip from someone who struggled with this for the longest time.

Nice vidio's
wish I had a track track's like that to run on

Hope to handle like you well better some day

mine like farm fields fresh plowed

Just saying

Thanks for your help

If you run yours level
Wont that turn your rear to the infield in the corner
breaking traction on the rear tires?

Isn't running a little less stagger and a little rear steer IE 1/8" to 3/16" rear steer better?

Or Just another way of skinning the cat?

Just asking your opinions??

IMO, just another way of skinning the cat. Lol And with the lowers level, you will have the least amount of roll steer possible. If your wheelbase is square to begin with, the ONLY WAY it would steer toward the infield is if your RR rolls farther than your LR lifts up and even then I think it would be very little.

Has anyone ever tried running the lower trailing arms at different angles ? The right one at one angle and the left at another angle ? I've never tried this, but was wondering if anyone has tried it ? Thanks, Ricky

currently run rr at 7-8 up hill and lr 2-3 up hill
car gets 4" comp. travel on rr and 2.5 extension travel on left rear
block your frame at ride height with jacks
take your spring out of the rear mark a line in line with
both axels hang plumb bobs and play with it see what it dose

I've been wanting to try different trailing arm angles to see what has the most forward bite. I run on a very tight 1/4 mile track that gets very dry slick. The turns are very tight. It's almost like two drag strips with tight turns at each end...Thanks for any and all help, Ricky
