I'm Building a GM Metric Cutlass for a 1/2 mile track.
What Wheel Offset would you start with?
Current car came with (4) 2-1/2" offset rims.
Would you Square it up with all 2-1/2" offset's and have a 3" & 4" available, to be able to pull in either of the rears, depending on track conditions.

We also can run a beadlock on the RR this year. With the Price of these I would like to buy only 1 (at this time), so this offset is fairly important to get right..

3's and a 4 on the right rear is a good place to start. If you just started drivin put 2's on the front to stabilize it. 2 for a wet track is good on a beadlock or you could get a three and use a spacer in the heat and take it off when the track dries out.

DMS CEO,
Are you saying to use 3 and 4's on the right rear? We ran a mustang last year and ran 2's on the right and 3's on the left. We switched to a 75 camaro this year and the folks at our local parts store told us to use 3's (rt side) and 4's on the left side.( I don't know if they told us this because they only had 3's and 4's at the time) The track that we will be racing at this year tends to be fairly dry for the heats and dry-slick for the main. Should we be putting a bringing the right rear in as the track dry's out?

No, 3's on lf, rf,lr 4 on the right rear. Especially on a Camaro that is the way to go.

I would disagree. On a heavy track run 3lf,2rf,2-3rr,3-4lr. As the track goes away you will want to progressively tuck the rr and extend the lr. I would go with a 3 rr beadlock w/ 1/2 spacer at start and come feature time remove the spacer and put the 2 off on the lr.

I would stay simpler in the beginning w/2's leftand 3's right and play w/ a spacer like bubba says . tire stagger and pressure are
important more so, I think

what should we do with stagger as the track dries out? I was told to run 1-2" on the front and about the same on rear. Also what about wedge? the car is currently set up with 2" lowering blocks on both sides in the rear. Should this be left alone or should we change this? (the rules at our track allow 2" as the max)

in general you want to take out rear stagger as the track dries out. how much depends on a lot of factors. I've raced on some tracks where 3" was good for the heats and 1/2" to 0 ( or even reversed) was right for the Main.

Your track may not change as much.

Taking out rear stagger will also increase your crossweight which is also going to make it easier to drive when the track dries out.

On stagger as the track dries out, you need less stagger.As far as front stagger I never run more than 1"

I never run ant rear stagger if I can help it, I HATE the way it feels. I also run the same front stagger all night. We used change the left front (go to a smaller tire) for the feature but got to tired of the work every night vs. very little change. However-I agree that if you are using stagger to go with what has been posted so far.

I would like to rescend all previous statements. My vote goes the the OUTLAW as crewcheif of the year!!!

let your scales be your guide. pick a combination of lowering blocks and springs spacers that give you the proper ride heights and static crossweight.

Your proper ride height is dictated by the track you race on and the spring rates you choose.

Your proper static cross is dictacted by so many factors: rear and left weight distribution, spring choices (and how they effect your roll couple distribution), driver style, track condition (and shape and banking), etc.

in other words ....

find someone who has had some success with a car that is similar to yours on your track (someone who has moved up to the next division can often be a willing and usefull source of info), get a good starting set-up, then taylor the set-up to suit the car and driver.

good luck,

A good place to start is 2inch on both fronts a 2inch on rr and 3or4 on lr for a gm metric car you should have 1000 lb spring in rf and 900 lf and 175 rr and 200 lr for this to work good (26 feature wins 2002)
