[QUOTE=ghostshadow,Aug 28 2010, 06:46 PM] do you feel your front roll stiffness is too high now?

 

So who else is driving their car to Lincoln, on their competition tires?

 

Driving to Lincoln from CT on my star spec's. Though when I get there, I'll be putting on Hoosiers.

 

Here's an update from the last MidDiv at Lincold this past weekend.

I had a horrible start on Sat. I found out that my alignment was off (no thanks to Jensen Tire), corner ballance was off, ride heights were off and we had fuel starve for the first time. Took the car back to Omaha and spent 3 hours re-doing the alignment and corner ballance. Sunday was much better with the car handeling the best it has all season.

I've closed the gap on Nick J to about 1 second now (on 60 sec course), and considering the other mods he has done, I feel pretty good about that.

 

I guess I can add my notes too.

Ran last years National's courses. East was exactly the same, West was slightly different due to some pavement break up. Ran first heat - on top of the exact same lines as 1200 people did last year. Needless to say, there was very little grip. The car worked much much better on asphalt in St. Louis. We had a hard time feeling the car. We had perfect steady state balance and slight throttle steer on asphalt. At Lincoln we had vague skittishness and a throttle on push - albeit the good kind of throttle on push - where you can still steer the car, it goes where you want and it allows you to roll into the throttle quite early.

We made some shock changes to try to get some sort of balance back. More compression made the car dig in slightly better at the expense of forgivability and the ability to roll into the throttle early. Andy liked it, I didn't. We made some front rebound changes today and I couldn't keep the rear end behind me. Ended up going back to basically what we showed up with before arriving in Lincoln. I'm still kinda confused on what to fix for next week. The car is still skittery and the mid corner balance isn't as good as it has been.


I guess what I'm trying to say is, bring a game plan and all your setup notes, this surface is very weird. I feel like I left about 1.5sec out there total. At least 7tenths on each course if not more. Got to get the head in the game and the car where it needs to be.

Saturday - East
Nick (59.7 - about 1sec quicker than ST last year - fixed mount after this run, sorry about the tilt partway through the run)

Sunday - West (altered so hard to compare to last year)
Nick 60.7
Andy 60.1 (dirty)

Cruddy quality - wasn't sure which resolution to pick with both vids on same screen - didn't want it to be too wide and distorted.

 

I'm amazed you didn't get into 3rd on the East course. With how it drove last year I would have expected it.

Why didn't you go to 3rd on West? The second straight across the top is fast and there is room in the corner at the end to drive it like a sweeper.

What is your limiter set at?

I've been driving my competition tires since I put them on my S. Our "local" events are all 60-80+ miles away. I'll be driving to Lincoln on my Dunlops, with Hankooks on a trailer, but I haven't decided which are my competition tires.

 

8500.

West:

There wasn't enough room to try to get the downshift done, turn into a sea of cones, and immediately start feeding the throttle back in. Plus it was only like 6-7hits before having to lean into the brakes. So there wasn't a whole lot to be gained.


East:

On my other runs I was hitting the limiter really hard coming up the hill after the long left hand sweeper, it was just one maybe two pops before hauling it down for the right hander. If the car was handling the way it should be, then yeah I would have been on it more, still wouldn't have shifter to third though.


Same here on the competition tire thing. One of our sets of Hankooks has at least 2000 street miles and 100+ runs. Still have more than 6/32nds of tread and no signs of falling off. However I will be trailering it to Lincoln.

 

not MY fault you didnt setup a trailer... i am bring 3 full sets out there.

 

Me too! But I'll still be slow.

 

I am.

1500 miles, each way. Driving out on the hankooks. Bike rack in my chase-race hitch with a pit bike, extra swaybars, and the race muffler.

I’m bringing an oil bin to do an oil change when I get there.
