I'll agree with Loren it was a nice run. I'm curious what the mistakes you saw were?

I feel like my lines were wider than others. Some areas I went towards the outside to set me up with a nice fast flow but compared to the other fast people, I saw they were staying closer to the cones. Like the first left hander after the turn around(the turn around, right hand into the little straight and then left) , I went towards the outside on that straight between the right and left. While in Kens video, he stays close to all the cones. I think im focusing on going further out than I should be which is making the track technically a little longer.

The fronts were squealing for days on that course. I didn't make any changes to the suspension(besides changing some axle boots but that technically shouldn't affect anything,unless I did it horribly wrong). The front felt like they were doing most of the work and the rears, I did not have a moment where they felt wiggly. I thought I was only getting tire roll on the turn around, but I was getting it on both front tires, even some when it hit 40psi hot. I felt the tires after the run and the outside was def a lot hotter than the inside of the tire. I guess -2.5 might not be enough camber so I might just max it out which is like about -3.2... . When I took a ride with Rowen in his porsche, I felt his rears gripping a lot harder than mine, shockingly a lot more. I'm gonna assume that due to rear wheel and mid/rear engine layout. But Tim's sti has the same layout as mine and his rears felt like they were doing a lot work also. But again I can rant all day hahaha, just need a little work on the front and seat time

Ken wasn't quite on his game, and there were places where he clearly didn't set up enough. (like the turn-around, see how he has to make an abrupt correction at the exit apex where he really should have been on the gas way before that apex?) A better video to watch for this course is Joe Vance.

There's truth to what you're saying, you CAN set up too much and add unnecessary distance. And how much you setup is going to depend on what you're driving and how much grip you have. Philip and I were talking about this last night. His car (being that floppy machine that it is) requires a little more setup in places to make up for the time it takes for it to transition to the other direction. That's why something like Ken's car (with fantastic suspension AND fantastic tires) might not require quite as much setup as YOUR car.

You have to drive your car the way it wants to be driven.

As for your discussion of tire-loading. As you said that the rear is firmly staying put, I'd keep shifting the balance in that direction until it gives a hint of starting to let go. Then, either adapt your driving style to it, or back off on that adjustment a little. You need the front end to hook up as much as possible. That means making the rear stiffer or the front softer until the back end just starts to lose traction. Swaybars, spring rates, shock adjustments, alignment and tire pressure can all be adjusted toward that.

A wider line, in and of itself, isn't necessarily slower. But you still have to hit your apexes, and if you were too far from cones, and adding distance, yep, that'll make for slower times.

I love reading this stuff. Thanks

Joe's line is what I should've shot for. He does extend out "some" but not too much for a great line. His slaloms almost make it look like his car was going straight, would've loved to see a side view to see how close he was to those tires.

Only thing I can really do at the moment is adjust the rear sway bar, alignment and tire pressure, for the rear. For a course layout that have high speed sweepers I do feel my rear start to give at high speeds. My rear sway is set in the middle. So for course layouts that don't have high speed sweepers I might try the stiffest settings on my rear sway bar. For courses that have high speed sweepers, I'll keep it in the middle. The previous points event the car felt pretty amazing. Had a couple of long sweepers.

Remember, you don't have to adjust both ends of the swaybar the same. It equalizes itself in the middle. You can go one position stiffer on one end. You don't have to go "all the way" from where you are. There's another "in-between" setting that is perfectly usable.

I think that's pretty much most of the problems. Going too far out while trying to set myself up(added distance), and being a little off/not close enough to the cones when apexing.

I don't have an adjustable front sway, just the rear. I will have to add negative camber in the front though unless there is no downfall on running 40+ psi in the fronts for the tire roll over. But also the outer tire working a lot harder than the inner which I'm gonna assume the camber will help more than the increased pressure.

I usually post a bunch in the past event thread on my driving and what to work on. Glad to read someone enjoys it or the feedback itself(unless your laugh was sarcastic D: ).

Wonder if this type of stuff should be in another thread to be discussed and not clutter the event discussion itself.

Laugh wasn't sarcastic. Just needed something that pointed up.

"Both ends of the sway bar" means the left and right side of the rear bar. They don't need to be on the same hole.So if middle is too soft, and 3rd hole is too hard, do one side mid and the other 3rd for that finer adjustment.

Wow, did not know you could do that!

That's why I pointed it out!

And this is a fine place to discuss such things. Carry on.

You really need to show up on Mondays.

I'm on the Brandon side of town. I would go out if it was closer.

I took my wife all the way from from Brooksville and she loved it. Two other women showed up in tow. The food is great and the company is even better. You'll be home by 10:30ish. Fun to try and recognize people without their sunglasses and hats on.

Estep comes from Valrico almost every Monday.

I meant they were escorted by others than I. But you knew that

My Dr Referral keeps telling me to go see Alice tho'. I don't know anyone by that name?
