Does anyone run any stagger with their FWD car? Does it help, hurt, or no difference.

I've read a lot about that on 4m.net...but didn't memorize it. Just search under the mini stock tech forum, some of those guys really know their fwd setups.

Thanks. They sure have a lot of different opinions over there. I think I'm going to try the stagger for cross weight set up first. One more Friday night at home and the #@%* weather is already practicing for opening night. Rain this Friday and the extended forecast is for showers next Friday.

Yeah there's not really a specific way that works for everyone it seems. Sun all week in washington and rain on the weekends, go figure. My track doesn't open until June though...so hopefully the weather will be better then.

Is stagger the same thing as adjusting camber?

No. Stagger refers to tire diameter. A large diameter tire on one side and a small diameter tire on the other side helps the car turn. Camber is tipping the wheel to help make it turn. Watch a motorcycle go through a corner. He leans the bike over essentially putting camber in the wheel to help it turn.

What type of track are you running? I've stopped at 225/60/15 front passenger and 205/60/15 front driver side. Car turns very good now but you do have to work a little to straighten her out. Makes it break loose the rear. I feel that my car is much faster than others now. FYI seem to have problems with axles breaking alot though. Hope you have better luck. GPS no more push, and Thunderbird very little.

We're running a 1/3 mile high bank clay track. Our rules state the tires must be all the same size, but not all tires with the same size markings are the same diameter. I shopped around until I found a tire that was just over 1" larger in diameter than the other tires on the car. I put it on the right front (FWD) and found that the tire temperature was a lot higher than with the original tire. I think some of the heat was coming from the tire tread design. It was one of those high milage type treads with the solid strip of rubber in the center instead of the whole tread being chopped up into little squares.

Shawn / Festy,

OK so you've got about 1" stagger on the front but what size tires are you running on rear? Same as LF or different size?

I'm still getting my car together...hopefully within next couple of weeks....& I'm thinking about P195/70/R14 on right side & P195/60/R14 on left side.

When I ran the 1" taller tire on the RF, all 3 of the other tires were the same size (1" shorter than the RF). I didn't really see any difference other than the tire temperature was higher. I'm going to cut some sipes in that center rib on those tires before I try them again. I put the regular (same size) tire back on the RF for this week and installed a different RR strut that raises the RR of the car about 3/4". I'll have to wait a week to see how that works because we got rained out tonight.

Do you guys think I would be better off running P195/70/R14's on the right side & P195/60/R14's on the left like I've stated above or running the 70's on the back & 60's on the front?

I know that I'm going to have to try to know what works best but anything that I can learn from others' experience will shorten my learning curve a lot.

Thanks,
Terry

I would put the bigger tires on the right side. I can see no benefit to putting both big tires on the back unless you have a rear wheel drive dragster. Since we only get 3 or 4 laps of "warm-ups" to test the car before races, I make my changes at home. After warm-ups, we decide if the car is better or worse. If it's better, we leave it that way. If it's worse, we change it back to the previous week's setup. The only adjustments I make for changing track conditions is tire pressure.

If you are allowed to lock the differential then use stagger maybe 1 - 1 1/2" circumfrence smaller on the left. Without a locked differential stagger only changes cross weight. Since with out a locker the car will send power to the left front this may be where you need the larger tire and some more weight. A stronger spring on the right front will help to keep weight on the left (driven wheel).
