The front GTR shocks are 50 mm shorter in overall length compared to the GTS-T or GTT versions and you have to make up spacers (refer attached picture) to fit on top of the top mount to fit PSS9's.

Hoping for some more progress this week - I'll keep you guys in the loop. I'm like a little kid in the candy store right now, checking out my mailbox for the AusPost 1st notice.

Subscribed :) What's the spring rate? Did you get to choose?

No - PSS9's come with the set springs and valving to match. Stock R33 V-spec is F:5kg/mm and R:4kg/mm - and with PSS9's they are F:7kg/mm and R:6kg/mm with the ride height 40mm lower, and of course then it can be adjusted up and down by another +/-30mm or so..

Hmmm i've got 8.2/6.4 Teins ATM that are still bit too stiff... 7/6 with the great bilstein valving should be very nice. I just need to get someone in sydney with them to let me ride shotgun!

I think people are (mistakenly) assuming the PSS9 valving is as good as the non adjustable Bilstein valving. It isnt.

Damn - is there much difference? How would you rate PSS9 valving compared to others in the <$2K range? It would have to be way better than my Tein NAs right?

Well I wouldnt because I dont reckon that any cheap (ie <$2k) adjustable shocks are actually any good. They all tend to have the same issues - the adjusters dont adjust all of the damper curve, they dont do it in a very repeatable manner, they dont do it in a linear manner, they vary greatly from shock to shock etc etc. If you seach google under images for PSS9 damper curves and the shortcomings of the shocks you will dig aup a bit of chat. The Bilsteins are not alone in having issues.

On the other hand a fixed damper can accomodate a good range of spring rates.

The bottom line is: how many people get the damper curves with the dampers and understand enough to translate that to a better setup? Not many I would wager. Most people end up by screwing in too much damper force anyway and having a pretty horrible setup.

Better off talking to proper suspension people and getting B46's re-valved if needed.

Paid my taxes the other day so the grand total now is in the $1400 range - so they have been released from customs yesterday and I'm awaiting delivery early next week :yes:

Will keep you guys updated how it all goes.

    • Initially I thought having a pair of Recaro seats would be a big bonus, it turns out these do get a little uncomfortable on long journeys (my fault, not the seat). I had a look through the GSM Performance website at reclining seats and booked an appointment to visit their show room. I got the Recaro Sportster CS for the R34 from here, was very happy with the service received so of course a re-visit was in order. Unfortunately the two Corbeau seats I had chosen aren't on display but they had 4 other options available. Two seats dug into my back, one dug into my legs and the other was perfect. I also found out that Recaro seats use a larger bolt pattern so some adaption was required. Luckily GSM offer some universal adaptors that should solve this problem. I searched the interwebs for price comparisons and Corbeau themselves were the cheapest at £300 cheaper (for the pair). I asked GSM if they could price match, unfortunately they couldn't. I later received an email saying Corbeau would honour them the same discount, but the purchase was already made. I did however order the brackets from GSM, both arrived on the same day. I started with the passenger side seat, knowing this was going to be a little trial and error. There are 3 mounting holes at the front and 2 at the rear on these JURAN Racing seat rails.  With the adaptor brackets mounted, the allen cap bolts started to push into the seat, NOT GOOD!  The rear mounting holes lined up but there were issues at the front. The holes were 1/2 hole out, so the brackets got a tickle with the drill to modify the holes. The supplied bolts weren't going to be long enough and a spacer was needed to stop the adaptor bars from bending. A local fasteners company supplied be with some nylon spacers and longer bolts (M8x30, although these will be replaced with 35mm long shortly) A before and after I pre-drilled the front bracket before making a start on the driver's seat to save some time. And in no time at all that was in the car too. The all black seats have transformed the interior and these are MUCH more comfortable. The only downside with the new Corbeau seats is I sit a little higher, but I'll happily accept that over discomfort. The Youtube video can be found here: https://www.youtube.com/watch?v=wPyttKPktXA
    • All 3 I guess. The car came with the JASI Aero 4 door Type R Full Kit unpainted so this was one thing at the top of my list to complete then I noticed there were body panels parts for this kit so i picked them up along with some black mesh to fill in the front bumper and front side air vents. car is at a paint and body shop atm completing this work. Next I will be addressing the internal bells and whistles, great summer project I can do with the kids.  full interior removal - ,boys car sound deadening - pads and spray ,boys stereo, sound, lighting - Big 3, GTT or bigger alternator ,kids head lining - dye black add star lighting mod ,daughter. That's it for the next 5-6 months. I have some motor maintenance  work i have to plan out. oil filter relocation, gaskets, mounts. beyond that, mind is starting to turn over if i can use a DET intake plenum, block off turbo ports & pipe in a air intake.      
    • roller coaster of a ride. Alarm system was removed & main harness was repaired where possible. still no fix just random successful starts. moved on to the replacing the ignition switch and relay. well all this troubleshooting & repair has been going on, the car is at a paint and body shop being pushed around. Ive been going down there on odd days after work to get it sorted.
