Budget '69 Camaro Track Car - NO WHINERS! - Page 90 - Lateral-g Forums

Sorry guys, Go Pro vid is a fail so I'll just run through the day session by session. Most laps I got in each session were maybe 4-5 at the most. As soon as I new I wasn't going to turn a faster lap I came in to log info and make adjustments and let me add trying to tune on a slick track was no easy task.
Session one started out well. 1st and second lap felt fine in the corners. I was relaxed and taking the car in. She felt really smooth and neutral in the corners. I started to get on er a little harder the third lap and she started to feel real greasy. Hot tires slick track. 4th lap I was coming up on three real hard. I came in from the outside for a late apex with an early turn in anticipating the four wheel drift to nail the apex perfectly. 1/4 of the way in the back end came around and I caught her just in time to be able to drive straight through the dry grass with 4 off and continue through four. Time to bring er in. Only thing that made me nervous was the shuttering of the steering wheel heading down the straight. It had never done this before and I attribute it to the new alignment set up for now but I will be checking, bearings, brakes, etc. The new alignment went from 1.8 neg camber to 2.5 and I brought the toe in another 32th for 1/16 positive toe on each side.

Time to hit the sack. To be continued......

Do you have a low oil pressure warning light? I'd rather just be able to see a bright light then watch a gauge...

You can make your own or

Adjustable one

Curious why you went 1/16 toe in?

cause he likes to make as many changes as he can all at once, just to keep me on my toes

If your asking me if I was sweating my ass off as I twisted wrenches underneath my car in 100 plus temps then yes, very easy

Just so ya know - I've always had all my wheels on the track even when I spun it in turn 9...

I can only imagine how greasy it was out there today. OMG.... Way too hot! The oil would have been oozing out it.

How hot were YOU??

Thanks Greg. To be honest the heat wasn't really that bad. It was a really dry heat and it didn't really effect me......but then again I am pretty acclamated to the heat since I spend most my time in the field. Track was slick but with the right set of shocks I could have adjusted for it. I believe the shocks I was using were inconsistent.

I've been playing around with my alignment just to see how the car reacts. Last time out I was 1.8 neg camber, 1/32 pos toe, and 7.2 castor. The temps on the outside of front tires were 7* higher than the inside.
This time around I went with 2.5 neg camber, 8.5 pos castor, and 1/16th pos toe. Outside tire temps dropped 4 degrees.
I think the shuttering of the wheel was due to the toe setting but i still need to get under there and take a look.

Mount a video camera of some sort to record your gauge readings.

So continuing on.....session 2 was a total bust. There was a delay at starting grid for debri clean up in turn 6. We got around one lap and then a red flag. All cars came to a halt. Somebody got 4 off in 8 and started a grass fire.

No adjustments for session three since I never ran session two. Oh yeah, dont think I mentioned that I took 2 lbs of air out of the rears for seesion 2 due to session 1 incident. Session 3 went well until the 3rd lap when the driver side started getting loose again. I wasn't going to get any faster so I brought the car in for adjustments.

I lengthened the arm on the rear sway bar on the driver side and took a click back on the shock setting to get ready for session 4.

Session 4 went well until third lap. I rolled through turn three fine but when I swung the wheel back for turn 4(back to back turns 3 right and 4 left for those of you that dont know T-Hill)The back end came out and I couldn't catch it fast enough. Ended up with my back end facing turn 5 cyclone. Fired er back up and brought er back in.

All in all it was a good day. I know the sway bar is doing it's job because the front no longer pushes. I may have had too much rear bar in it but I if I did I didn't catch it fast enough this time around. I also could have dropped rear roll center on the watts but once again another "what if".
Important thing is that I learned a few things and can move forward from here. Looking forward to the next track day.
