Maybe it's time for a rear sway bar???

This was taken at the last Car Guys event at Shenandoah (Summit Point Raceway).

looks to me like it already has one. Otherwise the rear wheel would hang lower, I think

man, that's a lot of grip!

Is it just me or does he look a lil out of position? I'm all about late apexing, but sheesh!

Nice pic! I've raised mine before as people following me have told me, but I've yet to get a pic of it!

Super sweet.

I've been running a 25mm Hotchkis rear swaybar on the middle setting. I would think with a stiffer bar, the rear would be even more locked to the ground and cause the arse end to start drifting towards the outside. Others?

I've moved my swaybar to stiff....we'll see.

Nice pic but a bigger rear bar won't solve your inside rear tire lift, IMHO, it'll make it worse. You might want a larger front sway bar or stiffer springs in the front or more droop in the rear with a softer sway bar to control the rear inside tire lift.

Looks like a lot of fun :) but those tire walls look extremely close :eek:

Those tires are sticky icky...

Dam dawg

Yeah I'm running the stock rear bar. I'm using ohlins (R/T) with hyper coil springs, basically the vishnu ohlin setup. My rear spring rates are 800lbs and my front is 700lbs. My suspension settings are as follows:

Front: 2.5- camber, 1/8 toe out

Rear: 2.0- camber, 0 toe


With this current setup, I'm getting a good amount of understeer. I'm planning to lighten the car up (right now at stock weight) and maybe go with a different set of shocks to get more adjustability. Also I'm probably going to run more camber, maybe around 3.25 degrees. Anyone have any suggestions?

Also this track is very technical with a lot turns packed into each other and blind corners. With higher HP cars you almost have to late apex some turns in order to get setup for the next set. Basically trying to lay down as much power as I can, since this track is more for lower hp cars.

Yes they are. You almost have to pretend they are not there to get any good laps in. :lol:
This track also has Nurburgring styled carousal that is pretty tricky to drive through. I'm writing an article about the event and I will post more pics.

A rear bar will help with the understeer issue by taking away rear grip but won't do anything about the tripoding. Also in tight stuff, I'm a huge advocate of as much front camber as possible and maybe just a bit less in the rear.

I never got to run on the Jefferson Circuit nor the Shenandoah, but the main Summit Point track is a blast, especially downhill through the chute.

yea main down hill is amazing wait till you see the one in Watkins Glen... same style but almost double the speed.

*hijack* I know what you mean by Watkins (run that one as well) but I just hate all the armco on that track. My favorite has to be turn 4/5 "the Esses" at Road Atlanta though followed closely by turn 12 coming down the hill. (the 'ring of course excluded).*end hijack*

Before you change your bar, try increasing the fronts to -3 deg camber and reduce the rear to -1 deg camber that should help combat some of the understeer you are experiencing. Looking at the pic I would say ... increase front 1st ... test ... if still getting understeer reduce rear 2nd ... test ...

Also where are you experiencing understeer? corner entry? mid corner? corner exit? or all through out?

OT: I did an event with NASA @ Iowaspeed way, it was a roval, half oval, half infield technical race course ... concrete barriers, tires walls, sudden massive changes in elevation and an instructor that kept saying "go faster" when my tires were already lightly squeeling :eek: :D

I was on track with Ali when that picture was taken. The Shenandoah Circuit is a blast. I enjoy it as least as much as the main Summit Point track because it is so technical. Like a well-designed autocross course, it rewards patience and good car control over brute force. At places like Summit Point main, horsepower goes a long ways toward making up for slow cornering, but not at Shenandoah.

That corner in Ali's picture is the sharpest and most awkward turn on the whole track. You really don't think about the walls there since you are going so slowly, especially the one in the picture which the inertia of the car pulls you away from.

The wall that I worried about the most was the one without tires that you drift toward as you come onto the front straight, which is just down an embankment should you slide over the curbing. This is a pic of my car at the same event this past weekend:

Most of the time it's during mid corner. I try to keep the mentality of slow in and fast out, but sometimes it feels like I can't get on the power until I'm right at the exit point. I can push the car, but what ends up happening is I over work the front tires to the point they get greasy.

I like the idea of first getting more camber out of the front and then seeing how the car reacts. I want to reduce the weight of the car to also see if that help improve stability. I'll try to take things step by step to see what sort changes will affect the car's behavior.

I also took some in car video, which should help everyone see/hear what the car is doing. I'll post that up after I finish editing it. (I've got a great shot of EVO8LTW's camero wiggling through that same turn in the pic above.)

Thanks guys for the suggestions. I'm still pretty new to all of this and it's good to have a group of experienced people here to help. :)
