me personally no didnt need to. but a mate of mine has, he did math to work it out, not just same amount as a riser bush.

Did you raise the UCA the same? or only the LCA? Im assuming you did it in a R32?

this thread has got some good information in it. Can I please ask if someone who has made some of these offset bushes up can you please pm me or post up a drawing of these bushes. I have a r33 cradle laying around im pulling the cradle out of my r32 anyways... and I'll machine the bushes myself, and I havent got a diff or arms yet, so I'll just purchase ones to suit the r33 cradle.

Then hopefully r33 coilovers will fit? Or is the difference in them on the upper mount/length. My r32 ones are shagged and I have r33 hks coilovers here too :)

i dont think by changing the subframe you will be able to use r33 coilovers

Ive installed solid alloy subframe bushes in my 32 gtst, and installed it flush with the car.

I also added a whiteline swaybar. Combined with the subframe being raised and the thicker swaybar, my swaybar is now hitting a seam on the body of the car....

I need the swaybar to move freely, so im wondering if you encountered this problem with the alloys?

I've never installed these bushes before but I'm going to say, double check the sway bar is installed properly, and if it is, I personally would just pull it back out and hammer the floor in a little bit...

sorry for the late reply but i have been working on the front suspension all day..

i took some photos, i think i will need to make a metal spacer about 10mm thick (b/c thats how much approx the subframe moved up) so i dont hit the body work. that and hammer the floor. i cant grind the floor b/c it will make it weaker.

sorry if the images came out poorly, they look ok in photo viewer but not good in paint :D

i test fitted the swaybar, but the screws to the bracket are not all the way in, so i will have less room as seen in the photo when they are tight.

any imput would be great, but if no suggestions i will make metal bracket and hammer floor as stated above and let you know how i went.

got it booked in for corner balance etc on tureday, i hope i make it!! :P

hmmm must be due to the whiteline bar.. mine is a cusco one and still has heaps of clearance.

either way. spacing it down is the answer and wont affect the operation of the bar either.

just had a thought that should've crossed my mind a very long time ago.. I'm not sure if the r33 gtr subframe is different but if it is I'll need it as my car is a gts4.. can anyone confirm?

bare sub frames are the same gtst/gtr/gts4

All the same dimensions, I used a GTST subframe in my 33GTR while I did some work to the GTR subframe. The only diff I could see when I had them both sitting on the ground next to each other is the GTR frame has a stiffener welded onto the top of the curved section on each side. Kinda like a double skin, I have pictures somewhere but can't seem to find them.

      Short shifter r34

      By PLYNX · Posted

      Don't do it if your gearbox box has already having syncro issues. The short hifter will put a greater load on them. If you must I remember Nismo did a shorter shifter, with the top part being physically shorter and the part that went into the gearbox was the same as stock. In saying that I've had a C's short shifter (I think) in mine for many years, which was given to me as the previous owner was not sympathetic to the gearbox. Thus forwarned I was careful and had to modify my normal changing style. You have to be super accurate with your clutch and shifts

      R32 Sedan - Grip and Drift (have my cake and eat it too build)

      Well, after a week of daily driving and having to crawl out between the wheel and the side intrusion bars. I got myself a quick release setup. I went with an NRG short hub and Quick Release with some cute heart cutouts on the pull tabs. Nice and matchy matchy with the rest of the interior accents I have going on.  The only downside is the total stack height even with the short adapter is longer than the old HKB boss kit. Luckily I had some adjustment left on the column so move the wheel away.

      stock shifter with new bushes, springs and cup will improve it. Gktech do all the bits. The opinion as the years have gone on is the redline is not great in old gearboxes.

      Short shifter r34

      By drifter17a · Posted

      Hi all   what short shifter do you use on your skykine r34?   my synchronous does have a problem and i was getting huge delay and grinding sound between 2nd and 3rd, did put shockproof red heavy stuff and it is great now/ no issues   would in your view short shifter screw this up?   people seems to suggest/ use cube short shifter and there is standard and premium. Seen review of premium as much better and less play. Thoughts?

      R34 oil and timing belt change

      By GTSBoy · Posted

      Yeah, there's a bit of a density and friability difference between pebbles and any of those other things. Silicone will definitely float in oil and so will be mobile enough to move around. Although, again, if it is upstream of the filter it really shouldn't go any further. I would only ever worry about silicone when it is in places downstream of the filter. Upstream of the pickup is a whole 'nother matter. We've all seen what that does. I have seen the most abominable crap settled out in industrial gearboxes, trunnion lube systems and the like, without any sign that any of it has touched anything in the machine. Just chilling in the bottom, waiting for the inevitable operator error that causes the whole machine to need to be dismantled for repairs.
