Yup.

Yup S2K did it all the time on sticky tires, kind of annoying with shitty diff because zero wheel drive at that point.

Chris,

Do you think this would feel like a slipping clutch from the driver's seat?

on my FWD car that's what it felt like....slipping clutch.

Somewhat it does, yes. Not exactly though. I always could tell in auto-x. Come out of slow corner mash throttle, nothing happening... then wheel spin, then go time!

would feel like slipping clutch but smell of tires.


Get an OS giken diff. :)


Oh, and stiffen the front sway. You have a lot of roll in general... I wouldn't say its too much rear... more like too little front.

Sounds like driving a turbo miata... :lol:

Chris,

Well, it would be about the same as lifting both rear tires off the ground and stepping on the gas (ZIIIIINNNGGGGG!!!) unless you have a clutch type LSD.

Soften up the rear end and let it squat down on the rear tires.

Same reason why we pull the front sway bar off when tracking a FWD car.

I used to run the front bar stiff, but I've had it on soft for a while now and I kinda like it.

I guess I could stiffen the front for autox and put back to soft for track.

You could stiffen the rebound on the rear shocks to slow the weight transfer to the front too. A stiffer front bar (or softer rear bar; either one upsets the roll stiffness distribution) might limit your ultimate front grip. More rear spring less rear bar would help too, but you will have a harsher ride.

This is why shock tuning happens last.

You try no rear bar yet?

I'll experiment with it a bit at the next events in St. Eustache.

Schmoo I ha the same issues on my car. Ended up disconnecting the rear bar and it helped a ton. Then I got stiffer rear springs, aero, and reconnected the swaybar.

I love no rear bar

Yup, my car does that at bogie, disconnected rear bar helps a lot, but need to play with spring rates to fully get rid of it.

I have 3 levels of adjustment available at the rear:

- soften FM bar,
- install stock MSM bar, and
- no bar

I'll try things out and see how it goes.

Thanks everyone!

I'd try the stock MSM bar, would be a good half-way point between the FM bar and no bar at all.
