car too high?

After looking at all the cars at Solvang, it looks as if my car sits a bit too high from the rear comparted to all the cars at the show. It also sits higher than my parts car? The shackles were flipped on my car, but I fixed that, although it did go a bit lower it is still a bit high. Any ideas?

The cars fitted with the Nismo rear competition spring will sit lower. My bumperis about mid calf. I believe that late model stockers are a touch higher than 65~67.

I took some shots of the 67.5 and the 66.

Hey J,
It could be your shocks... I have gasadjust and keep them just a lil lower than your. Hitting freeway dips at speed will cause you to bottom out and that's hard on my back. Looks good to me but the slammed look is very attractive.

Matt,

I have KYB Gas-A-Just. I dont know how to adjust them?? Any ideas? I would like to drop the car a tad bit, but not now. I want to drop the front as well, but at farther time along the road.

Ok Cool! Yeah the 66 is harsh! I have a feeling it will never be on the road, but parts from it might! Thanks for all the feedback! Keep on roadstering!

Awwwwwwww, cra.......er, crud! The rear on my '66 looks like your '66. I figured my so-rusty-crusty-you-cannot-read-the-label shocks needed replacing, and Mike Young springs to lower the front. Guess replacing/rearcing the rear leafs gets added to Da List.

What're the rough costs of that?

Gas-Adjust do not adjust. They are high pressure gas shocks. They will increase your spring rate quite a bit. They were designed to work on full sized 70's vintage Dodge cars. The damping rates are wrong for our light weight and stiffly sprung cars. On my race car I was getting a pogo effect. The high gas pressure in the shock would resist compression but would assist in rebound. The stiff springs could rebound from a bump very fast because of too small amount of rebound damping in the shock. The effect was a very sharp impact when hitting a bump and then the tire would slam and pogo off the pavement. I caused the car to skitter across a bumpy corner. The high gas pressure also raised the ride height of the car. I switched over to Carrera hydraulic adjustable shocks and the skittering stopped immediately.

If you aren't racing then I suggest keeping the KYB's and accepting the fact that they work fine on the street but not on the track. You can get a lower ride height in the rear by installing comp rear springs, install lowering blocks and longer U-bolts in the rear, or switching to the low pressure KYB GR-2 or Koni hydraulics.

The 66 springs are a popular swap in to the later cars because they have a higher spring rate and they lower the ride height.

Ha! you too? My bouncy-bouncy front end began when I fitted my car with the comp front springs. I've got a set of carrera's still waiting to go on. I've had them for over a year, but, to lazy too fit them.

I took the four bolts out that hold the lower a-arm triangular spring perch/bottom plate. The spring and shock can slide out the bottom. I then installed the new shock and spring and put the plate back on. It saved me from having to separate the ball joint or mess with the lower a-arm mounting points (which will mess up the alignment). You have to remove the swaybar to do it this way. I've also heard of people enlarging the shock hole to get the larger shocks to fit.

Andy,
Do you know if there was a coil spring isolator on the top and the bottom of the spring? I removed my springs and only noticed one on the top, but anything could have happened in 35 years.

If only one on top is stock, can you add a second one on the bottom to?

I've disassembled several and none of them had a rubber pad on the bottom. I think they were only on the top. I don't think one will fit on the bottom because the spring fits over a hump in the bottom plate. The clearance is too tight between the spring and the hump for an isolator.

What are the Carrera shocks? For a Porsche Carrera?
