I just replaced the entire suspension on my sc400 including new control arms, steering bushings, end links, tie rods, all other bushings.

Two weeks before starting this, I sprayed each nut/bolt with pb blaster.

A week later, sprayed everything again, and again when I started the replacement. Three times total, and I believe this saved me a lot of trouble.

I also installed the Bilstein shocks/hypercoil springs (gixxer_drew) setup.

This took about 8 hours including alignment. Two people with a rack and air.
I mostly just did the toting and dragging.

Only real problem was a stripped front lower control arm bolt.

By the way, the dealer had to order the bolt, and said that the front and rear bolts on the front lower control arm are different part numbers.

I do not wish to slam the car, but rather have a good solid setup for everyday street use. I will likely never track the car.

When I started, the distance to the top fender well was 27 in.

I set the after at 26 in. for a one inch drop.

I am not sure and unable to find what the standard height is. I am concerned that the old suspension may have sagged and that I really have more than a one inch drop.

I bought the sc400 new, and it now has 250k miles. It has the stock 16x7 wheels and tires.

If anyone could give me any insight on this, I would really appreciate it.

Thanks,

Alan
