Default Cross Weight, and stuff.

I'v driven my car about 1200 miles now. Still getting used to it. But I didn't think the car felt that precise. I had some time today to mess with it.

I raised the front ride height about 3/4". I managed to scrape the bottom of the scoop a couple of times.

Then I put it on the scales. This is the baseline.




I made a minor adjustment to the left front




This is with about 1/2 tank of fuel, and no weight in the driver's seat. Sometimes I'm in the car alone, and sometimes not.

Unfortunately, there is no adjustment for the rear, or I would have taken a little weight out of the right rear. If I was racing this car, I would make that adjustable.

I also checked the front end alignment. Caster and camber are fine. But it had 1/8" toe out. I changed that to 1/16" toe in.

Did it help? YES! A noticeable improvement in feel and ride. I like it.

For an exceptionally entertaining corner-weight thread, click here: Best way to adjust rear coil overs for proper height on my SPF You can read all eight pages, or skip to the very last post, which sums it up nicely.

Yeah, I remember reading that years ago. Adjusting the corner weights on a short wheel base, light weight car is an important step in getting it to ride and handle correctly. As you can see, the car was pretty far off from straight. I improved on it, but didn't get too OCD about it. If the rear springs had been adjustable, I would have spent more time to get it closer. But only because I had it on the scales already.

I just took a short drive this afternoon. But it really did feel better.

Now, to work on the brakes.

I took a 220 mile ramble through the mountains today. What a difference! Not quite a new car, but certainly much improved. Very stable in the corners, very smooth and predictable. Much more settled. I didn't think it would make that big of a difference, but it did. Now it makes me want to go out and play with it some more, to see if I can get it any closer.

Now, to work on the brakes.

Are you sure about no adjustment for the rear? My car does they are hard to get at had to remove the rear wheels to get at them.Should be at the top of the rear springs that is where mine are.

Is there a jacking pad up there? I couldn't see one, and assumed it was a fixed spring pad?

I may have to re-visit this when I get some free time. It probably wouldn't make a noticeable difference. But it would give me something to do, and helps satisfy my OCD.

Rear is adjustable at the spring pad.
