Laugh at my body lean and lack of LSD

And don't worry, I probably won't be able to catch up to you for another event or two

old, hard tires will smoke like that, and certain brands smoke worse than others as well. all depends on the rubber compound.
I've had several sets of Kumho 712 and others that barely smoked at all, even when I was doing a 2nd gear burnout. But my Kumho MX lit up like a pothead at 4:20 the one time I spun them in 1st at the track. (granted, they were so hot you couldn't even touch them when I got back to the paddock, but still.)

with weight transfer comes body lean. it's simple physics. more weight transferred to the outside wheels means the outside springs will compress and the inside springs will extend.. Even at 10kg springs (I'm guessing roughly 550lb/in without doing the math) that means in a 1G corner, you will be putting an EXTRA 1000lb on your front outer wheel. that weight has to come off somewhere, which will be the inside front wheel.. so almost zero on your inside front, and about 2000 on your outside front. at 550lb/in on springs, that meand there will be roughly a 4" height difference between corners.
YES, the CAR WILL LEAN. no matter how big of a spring and sway bar you're running, the car will lean.
the huge sway bars also magnify the problem, since they try to keep the suspension from changing. when the car is leaning hard in a corner, it's going to compress the suspension on the inside wheels, possibly lifting it off the ground when the sway bar is pushing up more than the body weight is pushing down.
remove the sway bar and you will have more body lean, but you will also probably pick up the inside rear less than if you had the bar installed.

I agree, it will lean...but not enough to lift a wheel. The problem went away with SFCs, which leads me to surmise I was experiencing chassis flex. Now, with the 1,2,3 SFCs it seems totally impossible.
not to hi-jack the thread...but i dont tell them that i have a Lower Tie Bar....i stay in STS....until they notice something that they make me move out of STS i will stay there....i really need a RSB and SFC's

the real test will be in autocross this weekend.....I'm actually hoping that times will improved thanks to better turn-in (I definitely have better turn-in, that is certain)....(hopefully the ypipe and removed intake will help too).
In any case, I have a "master plan" for the half of the tie bar that is sitting lonely in my basement (yes, I know I have defiled the fabulous LTB2 - sacrelige)...more on that if/when I carry it out (hint: involves custom SFCs)
-for now, don't ask....really.in any case, at least it puts me back into STS if I run SCCA again soon.
really....no excuse for this, but if you can't experiment with things on the car (and risk doing something counterproductive), then what's the point of modding at all

I get a "little" more body lean into hard corners now, but I just cranked my illuminas up and that pretty much made up for it (as did the ES lower control arm bushings) so I'll call it a push for the moment.

Or at least wait until you know WHEN you're getting back into SCCA
(Don't take me so seriously guys

The money I'd spend in packing/shipping away the stage 2 + the money I'd lose with it being "used" + the cost/shipping of a "new" stage 1 bar + having to wait for a buyer, etc...that's too much trouble and not worth the few bucks I might make on the transaction....I make enough money to let a few bucks go down the toilet every so often for the sake of convenience.
Like I said, I have a project in mind...just gonna take a while to get a design together, get someone to make it, and stash some cash away to do it (no Matt, it's not what I was talking about in the other thread, btw)....if it's unsuccessful - I'll never say a word
and if it works, you'll know all about it.besides, now you have one less excuse when you get beaten
(j/k)
btw Nick...I didn't cut the bracing bars flush to the "now-stage-1"....I cut them off 3-4 inches out as part of my possible future plans.....a stage 1 wouldn't have worked for what I'm thinking of.....

So uh....when is your next SCCA event?

...I'm going to run NASA next year most likely, but I think their rules/classes regarding LTB are similar....

Coilovers and chassis bracing would have helped considerably, especially in helping remove understeer. The next time I would have went to the track, I would have probably ran something like Kuhmo Victoracers or RA-1's. Once you have been to the track a few times, street tires really hold you back.
Victoracers are not a legal tire for Street Touring Tire classes
