Yeak OK so you know the basic tradeoff then. More camber = better feel but more steering effort. I like the feel of 4* myself, FM style depowered rack.

So HHR is already getting that rough? Damn...
Since you mentioned it, how is your steering control on the front straight transistions at TWS?

Hustler,

Borrow someones data logger before you start changing stuff! Curious what kind of steady state cornering g's you are achieving. Would be great to see befores and afters when you start fiddling with ride height, spring rates, alignment, etc.

949's alignment numbers are a great starting place too.

Nope.

nope

running more caster also nets you better turn-in bite because of the added camber from the kingin's inclination.

I can't break more than 1.22 sutained lateral Gs at this point on 9's with nt-01s. It has to get better. I spoke with Emilio and I'm doing exactly what he told me. Unfortunately I don't have general access to a datalogger.

I'm running the middle setting on my FM 5/8" rear bar. The car is neutral on the slightly loose side and easy to throttle steer. IIRC according to the fatcat spreadsheet, my spring rates are slightly front biased, I like to be able to tweak the balance as needed with the rear bar. For example in the wet i should soften the rear bar, if i had selected my spring rates so that i didnt need a rear bar, my only option would be to stiffen the front, when generally you want to soften everything.

Honestly HHR is the only track that I have noticed any bump steer. I'm not sure when you were there, but the bumps are pretty bad. Goin CCW, in the kink, turn 6 i think, i would get wheel spin at the top of a bump at the apex and also put the tire into the top of the wheelwell at the bottom of the bump. I have a 2x4" shiney spot to prove it.

I'll put up some video, it should show how bumpy is is.

I take a pretty low line into turn 1 at TWS, partly because I run out of gear. I do not have any problems at TWS in terms of bump steer. Dont get me wrong, there is some bump steer, but its not bad enough for me to complain about it. you can kinda see the steering wheel in this video

Yeah OK that line lessens the transitions so I see your point. Still your bumpsteer does not look too bad from what I can tell. If you are hitting that bump at the inside of T5 it is not bad at all. It seems like your line took you over the bump but I did not see any movement. Looks like that first lap was a ~2:00 not too shabby from what I understand.

Though I have done hundreds and hundreds of laps at TWS on a bike (not exaggerating here) I have still not been on HHR. So is it accel/deaccel ripples, or the track settling, or both? Same thing happened at Houston. I made a bike track day there right after it opened and the surface was a freaking dream. Now, not so nice.

The track is buckling and have waves that are as big as speed-bumps. I was hitting them as moguls between the hairpin and the dam-turn.

HHR is losing a battle to ground shifting I think.

My best recorded on the traqmate at TWS 2.9 CCW is a 1:58.990. That was the same setup I ran at HHR, RS3 on 15x8.

Just out of curiousity, what kind of sustained G loads do you normally see on the traqmate?

I have my G2x on the shelf. No track stuff happening around here for a few weeks. You could borrow it for about a month pretty easily. Priority mail back and forth wouldn't cost much in the flat rate box.

If you're willing I'm down. I'd love to actually. I'll take full responsibility and pay for shipping.

Trey

I see around 1.2ish sustained on the RS3's.

1.4g sustained on NT01's. I only have 1 weekend on the NT01's on 15x9's so i wasnt pushing the tires all that much, I know theres more grip in them cause i never found the limit.

That's about what we see with those tires too with a slightly lightened car.

The RS3's amazed me too the first time we ran them on 9's. Shockingly fast for a "street" tire.

Hustler, keep a 12mm rear bar off the 1.6's. Don't listen to the guys running no rear bar. The better your shocks are, the more rear bar you can run, the harder it will turn. All the fast SoCal cars are running the 14mm rear bar off the MSM. With softer springs or shorter stroke shocks, the 12mm NA6 bar and a either the fat FM or 1.125 RB hollow will work.

Nice video tann3r. Its funny the car in your sig looks like a Porsche at first glance.

I'm ordering shit from you right now!!! lol

Sorry I didn't see you question about the damper settings. I'll have to check this weekend. I'm pretty happy with my current settings, but I'm still tweeking.

I use Tein Flex with 10 kg and 6 kg. How does that translate to lbs.?
