Ita 92 civic hatchback dx ?

Gotcha. FWIW, yours converts to ~1.25" diameter, .120 wall bar offered by speedway. In their range that's a pretty "middle of the road" bar so if you decide to go softer or harder, you may have some options thru them. I'm running the same size bar but with a bit more adjustment options on the arm length.

I ran my CRX at 500/700 and have to say that my Civic at 700/1000 is actually smoother over bumps... IMO, the higher rates pay dividends when you start hopping curbs as the suspension bottoms out less.

Both my CRX and Civic were/are drum cars. Are you locking them up under straight line braking at all? Or is the issue only apparent when one of the rears has been in the air? If it's the latter, I wouldn't worry about it... the small puff of smoke at touchdown shouldn't hurt anything at all. Its unusual to have rear drums adjusted tightly enough that you'd have premature rear lockup... this is b/c with them adjusted "out" too far, you'll have trouble getting the drum back over them. More often, I'd find that I needed to ratchet up a click or two on the parking brake to start pre-loading them as they got hot and wore as the race went on... what rear shoes are on the car? Stock type?

My son introduced the rear of his 92 dx hatch to a tree yesterday. Need parts?

The rear shoes are 913's from carbotech. I don't think they were locking up when i was braking straight. So maybe it was just that I unloaded that tire enough that it would lock. I was lifting the inside rear in a number of turns. I still have a lot of work to do before the car is setup anyway so I am not going to worry about it. yet. Also they were brand new and did not have a brake in period yet. Thanks for the help though.

We run stock pads on the back of the Golf and still get lock-up on the inside trail-braking into a corner. Anything with any initial bite is going to be a problem in that respect. (EDIT - on a FWD car)

What Kirk said. If you're having the rears lockup prematurely (i.e. before they "lift off" the ground on corner entry), you might want to try stock or stock equivalent pads to reduce braking torque back there.

will do. thanks guys.

During my SCCA School I locked up the rear tires ALOT, while still going straight, at turn 1 at Roebling. I scaried the hell out of my friends (and probably the students directly behind me) a number of times because of the HUGE amount of smoke the RA-1s were throwing up. I ended up replaceing the 913's from carbotech with Advance auto parts "good" shoes. That alleaviated the lock up problem in the rear. I'll just have to keep an eye on them and keep an extra set of shoes around just incase.

Our '92 H/B has completed its transition into an ITB DX. Drivetrain is built and dyno'd. On a brand new motor, it did ~4-5whp less than the typical "average hp/lb" ratio of ITB. I'm hoping that after I get it out and run a weekend on it, it'll break in some more and that power number will come up a little bit. As it is, you're not winning an ARRC in it. I may take it out, shake it down, and break it in at Mid Ohio during the Friday test day before the May 22-23rd National. If I do, we'll see how it's breaking in and how it's doing.
