Houston First Event Jan 2012, also have a question

[tukaniSVT]

Well, today was our first event in Houston, TX and yesterday we actually had our regional championship. Pretty fun, ran both days.

For today, we had 88 entries and was able to run 5 times. we usually do 4 in our region.

STF will be lonely for at least month or 2, but it will fill up here in the Spring and Summer.

This photographer was their and took some photos. Thanked him, since I didn't bring along my SLR.

My question, What do you guys recommend on fixing the back end pulling out?
I have adjustable KYB Shocks paired with H&R Race Springs and also have Adjustable Toe set at +1.0 degree.
My back end came out super easy, but way too easy as well. Felt I understeered a bit too much around corners.

I played with my settings on the shocks, but just didn't get it right to me.

Should I stiffen the front and soften the back to best return the understeer? Or vice versa?

Thanks.

Oh and here are the photos from the day.



Oh yeah, taking a cone for a ride ... btw, I didn't hit any cones for time ... that was a pointer cone. hehehe

Nice action shot and with 10% more cone!


Try the alignment/toe, and also go with a softer settings in the rear. If all that fails then maybe we should put the front sway bar on?

And damn it almost looks like your car has no roll lol

you get 4-5 runs for the entire day??
that's usually our morning heat! with 4-5 more in the afternoon!
i guess we are spoiled..

for me, getting the back end to come around is exactly what i want. i even trail brake at times to get the rear end to come around.
if you don't like it, i would first start off by playing with tire pressure. (i'm still trying to dial in my tire pressure) then move to shocks/sways

If the rear is coming out, its oversteer not understeer. I run my car with about zero rear toe. I think +1 rear could be adding to the oversteer...

I agree too much toe. Return to stock and then play with shocks, struts and tire pressures then try toe.

Thanks guys.

Paul, yeah, may think about putting the front sway in front after all and taking out the stock one. LOL

BTW:
Caster: 0 in front / -1 in back
Camber: -1 in front / -1.5 in back
Toe: 0 in front / 1 degree Toe-Out for back


Mark: yea, we had a couple of guys talk about you "Northern peeps" getting plenty of runs. Heck even OKC's regional gets 6-8. Us here in Houston we are loving the early finish, because a couple of years back even at 3-4 runs each we wouldn't leave until around 6-7 ... an ALL day event. And we use to have an average of 150-200 cars. That's alot of cars. So they stuck with that run set up and when the economy unfortunately took away plenty of participants, it gave us back time for those still running.

As for pressure, yeah, I was playing with it all day yesterday.

With these 225/50/16s, I was on average 34-36 up front and 38-40 in the back.

I do indeed love the back end coming out, but I think its a bit too much now.

wrc_fan, thanks for the link. I will read up on it. Yeah, I had a feeling, but I am liking the feel, it's just too much of it, maybe ask NTB to dial it down and see where I stand.

i would try lowering your rear PSI.. that should help.
i've always had my PSI in the front higher than the rear.. to compensate for the motor.

i think the biggest turn out we had last year was 120! we average 60-80 drivers. that explains all the runs! plus, we usually get fun runs after the actual event!

[sleepyboy]

definitely lower the rear pressure some more. Start at a base line and then work you way from there and note any changes that you made, made lol
