They started a stock mini class this year. I noticed that all the front wheel drive cars push real bad. Some of it is under braking, but most seems to be "power under-steer". Will stagger fix most of that, or do you have to drive a front wheel drive different.

Thank's for the info...Chuck

Its a combination of both. You have to set the cars up differently and drive them differently. Remember, power understeer is much like power oversteer in a RWD. When you spin the tire, inertia lets that end of the car keep going straight rather that turning the corner. So, you need apply as much throtle as possible without lighting up the tires and the FWD will pull you through the corner. You might start by braking a little sooner (before the corner) and not drive it in so deep making it push up in the middly. Stagger will only help if the half shafts are physically locked somehow, just like a locked up RWD.

a few things to try...
remove the rear swaybar if the car has one....
pump the rear tires way up(run smallest you can)
go into the turns on the high side if you can(corner exit speed is where it's at!)
you will have to drive with your throttle foot as much as your brake foot
it can be real challenging to run hard with the rwd guys since you are running different lines....try not to push up into them too many times or they will start wreckin ya

good luck!

Got a question for the front wheel drive guys. Have you tried locked differentials? Do they work? Do you need a lot of stagger? Did you lock lock it up by welding the spider gears? Haven't had a fwd yet but I might next year. Thanks SLEEPY

I run welded spiders in my scirocco...
I run on a 1/4 mile dirt track... I tried factory limited slip & open diffs, on that short of a track it will light up the inside tire if it isn't locked....stagger will help, but then it breaks cv's...it can be a real handful.... since your speeds are probably higher on a bigger track, inside wheelspin would probably not be as much of a issue... quaife diffs(torque sending worm gear setups) are avail but outta my budget
I'm interested in hearing what all you other fwd peoples have to say!

I found a book named "The Front-Wheel Driving High-Performance Advantage" Written by Jack Doo and published by Motor Books International. Lots of info on FWD setups and reiving techniques. It's worth a look.
