I've decided that the new PMC powerplant is going to show that the suspension in my car needs work.
So have decided to look into doing the S13 coilover transplant.
Clearly after adjustable height and damper.  ;)
Anyone know a good place to buy some? Second hand will suffice.
What should I be on the lookout for?
thanks, Simon

nissansilvia.com always have used ones coming up for sale. I believe the rear just bolts in but you will have to make the front work. Most of the japanese brands eg. HKS, TEIn can be rebuilt. I have heard good things about these coilovers

Fairly Cheap for the functionality you get.

Thanks Benny boy

For anyone interested
1 kg/mm = ~56 lb/in

Spring Rate Equivalencies

700 lb/in = 12.5 kg/mm
650 lb/in = 11.6 kg/mm
600 lb/in = 10.7 kg/mm
550 lb/in = 9.8 kg/mm
500 lb/in = 8.9 kg/mm
450 lb/in = 8 kg/mm
400 lb/in = 7.1 kg/mm
350 lb/in = 6.2 kg/mm
300 lb/in = 5.3 kg/mm
250 lb/in = 4.5 kg/mm

Can I get an expert opinion on what spring rates would suit my car for trackwork and spirited driving?
(not full on race, ie bone jarring)

I have just gone from 250lb to 300lb in my 240z it has turned out to be too hard and the car now severely understeers so I am planning to go back to 275lb but for a 280zx I'd suggest 300lb should be about right due to the extra chasis weight.

This ain't a bad price for new, but shipping is the factor I guess:

Its still an expensive exercise if you haven't got the skills or equipment to weld them in.

+1

But I think his setup was a rather involved conversion. It certainly gets results though.

I picked up a pair of HKS Hypermax performers 7kg & 8kg for a GDB WRX off ebay in mint condition for $450.

Just remember that you dont have to get S13, you just need the correct OD on the shock body and a top mount that can be swapped for the zed type.

Check out the thickness of the shafts on these bad boys:

Just gotta scout around, i couldnt buy good nick second hand coilovers in Japan for that much and trust me i looked! I went to Hasegawa in Tokyo and everything for S13 R32 was flogged and shiver or it was brand new and they wanted $1500+

Here is a Hybridz how to on an S130:

Are you doing this conversion to an S130 or S30?

what kind of work are we talking about to get the fronts in?
I am up to this stage on my Zed and am completely overwhelmed on what to do.

A friend of mine has a Taiwanese company making some weld on coilovers for R31 skylines which are almost identical to the Ground Control front coilovers and could make for an easier conversion:

I have a set in my car and they are pretty good and at $1300 it's not too expensive either. They have the same abilities to adjust camber, height and damper stiffness without removing them from the car like most conventional coilovers and you get to choose your spring rates. Considering S13 has the same front top hat PCD as R31 and R31s have 3 bolt rear top hats as well it might make for an easy swap if everything lines up (I don't know how similar S130 front suspension is to Z31 but I know that Z31 has the same top hat as R31)

Close but no. These coilovers you cut your original strut down and leave about an inch of tube, slide the new damper tube over the top and weld it to the base foot. Rather than grind brackets off an s13 coilover and machining the knuckle to fit the larger diameter tube. This means less machining needs to be done plus you aren't welding an oil/gas filled tube

Edit: Scratch that had another look at the S13 coils. The option I suggested above just has the brackets already removed. If you are going new then I would say it's worth it but otherwise backyarding ftw
