is there any other option to the Koni's as they are about $250 each corner

Loui

That does depend on the spring rate you are using. Koni's can be re-valved to suit heavier springs others :( can't.
I believe tokico illumina are good to 250lb and it might be the same for the kyb's hence this post.

Thanks Dimitri. I have the 6kg/mm or 335lbs spring rate. With the KYB's there seems to be zero rebound control.  Did some research on the koni's and they are now $630 a pair!  :o  Other members have said thet sectioned 50mm from the struts, which sounds about right to keep the springs captive. If this has been done what struts would they use as the koni's wouldn't fit  ???

50mm is alot to remove from a strut but if that's what you wanted to do, Koni can shorten the shocks too to suit. The car we be ultra low but yet still have a good amount of suspension travel.

By cutting out 50mm from the struts, I was able to use the old 240z front shocks on the back and a set of KYB's for toyota celica on the front. So I guess you should be able to get Koni's to fit.

Until I put a set of 6mm/kg springs for the back I can not comment on the damping (stupidly put soft springs at rear, and have not changed yet until new springs are ordered). Strongly don't recommend anyone else try this, as the ride is not good - like an old fishing trawler.

My 260z struts are 50mm lower than stock (front are same length as 240z remember) and the koni yellow sports were from a celica.....I have partnumber written down somewhere I will find it and post shortly.

Just to clarify its for the front they are 55mm struts with 6kg/mm springs, will go lighter for the rear to allow more compliance and good power down on exit of corners. Lime 6kgs in the rear is farkin heavy for the rear of a zed imho, what rate do you have in the front? The KYB excelg's wont handle it, mine were in perfect working order. My goal is to have sufficient rebound control and keep the springs captive at full drop if i'm able.  :)

I have 5kg's in the front, 4kg's in the rear. With the intention of replacing the rears with 6kg springs. The front still feels "soft" with 5kg's, but I will try swapping the current front / rear combo before I order some 6kg springs.

The 6kg feel nice in the front, quite firm but not rough, corners flat with minimal roll. I'll probbably go for the 4kg in the rear with koni's already in. Going for the koni yellow sports in the front as they should be able to handle the heavy spring rate.

Gareth, I HIGHLY recommend you get them valved correctly for the intended spring rate.
It's like only doing half a job if you don't...

Yeah, I've been chatting with the chap from toperformance about it and still have to work out the final rate required.  ;)  Apparently anything over 250-300lbs will require koni yellows or billsteins, Interestingly tokico illuminas are only rated to 250lbs.

That is interesting, illuminas are pretty stiff when you turn the adjustment up

I have also found some Kyb agx's to suit 240/260z same as the koni yellows and actually made for 300zx's so require a small spacer. They are 8-way adjustable and suit heavy spring rates. Also they are around $200 cheaper than the koni's  :D

There two versions, standard length 300zx kyb 8-way adjustable with auto vavling. Then there is the short version which is uprated 4-way adjustable with auto valving (requires a 25mm spacer on top) these were $480 + post. Part number was KYB AGX 365056, but I'm unsure which insert this is for. I got mine through Datsport and found them to be very helpful and  much better priced than the Koni's  ;)  Give Baz a call tell him Gareth sent you.

Quick pic of our sleeve kits fitted to the struts going into my KHGC110 (240K). We also used the HSD universal camber tops, cut and drilled to suit the 110.

6kg.mm front springs, 12kg rear in the 240K.
Don't recall what shocks we put in the front. Rears are HSD TT-type off an MX5
