P.S. Why do you think the car stepped out at 7:24? Was the car on the verge of free anyway? ... or did something different happen?

Car and driver are looking good and the motor sounds great!!!

Gae - Nice lines buddy, the last couple of laps looked quick, right on the edge of traction thru that sneaky T6 :thumbsup:

How's the gearing? Almost sounds like you're maxed just a little early on the front straight?

Camera's just don't do the crest of 9 and the run down the hill justice.

I'm waiting for you to hold it pinned over the crest in T5 :unibrow:

You look smooth out there... like you've been there before? :peepwall:

Glad the car and you behaved well out there.

Oops. Spoke too soon.... where's that new suit you bought? :rules:

I'll be running with Nor Cal Shelby October's Fall Classic.... they'll even allow Camaros to run!!

And also Laguna Seca (just a one day event!)

Well Ron.....I pretty much just took a half inch off the coil springs
Which loaded the front tires more, helping to loosen the car up.

and then added a 1/2" taller ball joint.
And increased camber gain.

Once that work was complete I took it to the alignment shop and backed out static castor and camber. Ths car responded by feeling alot closer to neutral which leads me to think I was running too much castor my previous track day causing the car to jack loose.
Sure could be. What's your scrub radius?

In addition...my outside front tire temp differential went from 4* to 2* which is good.
Good.

The car began to get free at the end of my second session and I'm thinking it was due to front tire wear
Hmmm. Why would front tire wear make the car loose? Do you mean something different than you wrote? :)

and the RA-1's starting to come in and give me better grip. To counter the free condition I began to lower rear roll center one bolt at a time.
Excellent tuning move for a loose car. Can you lower your rear ride height any?


By the time I got to my 5th session I had dropped three bolt holes
How far apart are your panhard bar holes? What is the range of adjustment you have? What is your lowest height? ... highest height? ... And where did you end up?

and the front grip was not effected which tells me front grip was getting better and so was the rear.
Front grip wasn't affected by the panhard bar moving down. Maybe the track gripped up. The rear panhard bar moving down works the rear tires more. In fact, if you go too far, it will make the car push.

I ran my fastest lap time the 5th session.
Cool. The video looks to be of session #4 ... and the car stepped out just once, but looked a "tick skatey" just a few times. When you lowered the panhard bar again for session #5 ... did that provide enough rear grip where the car didn't step out at all? ... or was the car still "edgy"?

Thoughts?

Thanks Sieg. Gearing is actually perfect. I'm tacking about 6200 at the end of the straight when I get it right.

Pinned over 5...........can you say airbourn :badidea:

No complaints about the gearing. Running 3.42's

Do share the coil over conversion plan, that's where I'm heading with my spare subframe. :thumbsup:

Gotcha.

up last season to take the push out of the car.
Ok. Now that you lowered the front end 1/2" you're loading the front end a LOT more, and it has gripped up the front ... making the car loose with the high RC. If you're not clear, dropping the front end 1/2" is a HUGE change.

With race cars, raising or lowering either end of the car 1/8" is a significant tuning change. 1/4" is a major change. 1/2" is a ton. It will affect the car's grip balance enormously. We don't do this a lot in the front of stock cars, because we're usually at or near the minimum already. So if we need a significant change, we might raise the rear & reset all the link angles.

It slips my mind ... that because you don't have any class rules ... you can do whatever physically works. Dropping the front end 1/2" is where you got the majority of the added front tire grip. The caster & camber changes you made played a smaller role.


I am now at a point where I'm getting more front grip so I am able to drop rear roll center to increase rear grip.
Yup.Yup.

I'll double check on how much each bolt location moves roll center but my guess is about an inch.
Ok. For discussion sake, post the max & minimum height from the ground ... and the difference from hole to hole.

Skatey would be a decent description of how the front feels now.
Is "now" session #5?
At what part of the corner does the front feel skatey?
Does the rear now have "good grip" throughout the corner?


I'm thinking it's a combination of still a bit too much castor that might be affecting my scrub radius
:headscratch:
What is your scrub radius & Caster at currently?

and I dont think the toe is the same as when I left the alignment shop
Hmmm. Curbs?

not to mention it would help to have a decent set of shocks.
Of course.

I'm going to verify if the alignment moved any next Saturday.

You know how I tune my stuff?? I drive it as fast as I can and if it starts skating around then I know I've hit the limits of traction -- either end of the car depending on which end is skating. When that happens -- I try to change my line in that same corner next time -- or I enter or exit slower. DONE.


HAHAHAHAHAHAHAHAHA

Had to get it done before taking my boys to the go kart place.

I'm sure GW appreciates the less technical term plywood but I'd call it OSB.:lmao:

Congrats on the certs:thumbsup:
