From what I've read on these forums, the standard R33 GTS25t center of wheel to guard measurement is 10mm higher at the front than the rear. I've also seen the recommended height, particularly with the Whiteline kit, listed with the front 10mm higher (ie 350/340). My Nismo springs on the other hand sit the wheel to guard 20mm lower at the front than the rear. I've noticed a few other Jap aftermarket springs set the car up like this as well.

What difference does this height balance make to handling, and ultimately what is a better set up for street use?

I've got a set of Bilsteins getting groves machined into them at the moment so I'm trying to decide the heights I'll use. At the moment I'm leaning towards making the front and rear even, ie 350/350.

For handling the recommended ride height for an R33GTST is 350mm front and 340mm rear. Which gives a 10mm rake, nose down as measured at the sills, just behind the front wheels and just in front of the rear wheels.

Cheers Gary, much appreciated. I'll set it up as recommended.

Out of interest, what is the downside of having greater than 10mm positive rake? Any ideas why the Jap springs sit the front so much lower, just for looks perhaps?

They run out of travel, the camber change angles turn to crap and they develop some bump steer. My guesses, the Japs have better roads, smoother tracks, they don't drive very far so ride conmfort isn't as important and they care more about looks than handling.

    • This. A 3d wheel alignment is like $120...just take it to the shop. Since theres probably multiple adjustments that need to be made after changing something. Mine has front/rear lower arms, traction rods, tension rods, camber arms, toe arms, front upper arms, hicas kit, sway bars and coilovers. I measure from the edge of the bolt holes on the originals and set the same length on all the adjustable stuff to dial it as close as I could to OEM. Took it straight for alignment; it didnt feel right at all...after alignment, it feels perfect. Similarly i've just changed the springs on another car; and I still needed multiple adjustments to bring it back in spec.
    • A full Veilside kitted JZA80 Supra in Meriken park in Kobe city a few weeks back
    • Its a well known brand in New Zealand; its a rebrand of the Rhino RAV3.  I don't know what the wiring difference *is* between the rev.1 (installed about 15 years ago) and rev.2; but as you say I would think its reasonable that it uses the same immobiliser relay circuits. I had a look but couldnt see a similar harness; but didnt move things around since I didnt want to mess with it   It was one of AVS well known Authorised Installers; I spoke to AVS themselves about it but theyre unsure hence seeking advice more so from the skyline community who are more familiar with the actual car and its wiring. Im in Auckland; but the installer is on the other side of the city so hes very reluctant to come back to even look at it to confirm something isnt connected into the wrong wire.  I dont want to drop the name since they *did* do a really good job for the most part. Everything is very tidy and he fully replaced all the alarm wiring, all the sensors, the wiring to the door motors, installed a switch which was never installed in the first place...really happy with the alarm install itself..just not this one issue. We all make mistakes, if it is the alarm, I just want my fuel pump getting proper switched, fused, power as it was; without having to shell out for an auto electrician to switch a wire and tell me it was the alarm. 
    • Even with the piston at TDC there was room for it to drop, but I don't think it can drop fully into the cylinder, the problem you have is that you need something pushing against the valve to hold it up so you have enough room to put the new stem seal on and the spring etc.  I used compressed air only because putting rope in the cylinder seemed a bit risky to me, I know people have done it countless times before like this. Overall it's a pain in the ass job. Honestly you'd probably be better off taking the head off because the risk of dropping something in the engine and the finicky-ness of it all is very stressful. If you are going to attempt it though i 10000% recommend a 36050 valve spring/keeper tool. I had both the traditional lever type and after doing 1 cylinder it was absolute pain to get those valve keepers in place, even with 2 people. That 36050 is amazing, you do have to push hard to get them in place but it works perfectly almost every time. Back to my actual issue I think my engine is just tired and old and the rings have gone bad. The comp numbers (cold, no oil) were: Cyl 1 -129psi Cyl 2 - 133psi Cyl 3 - 138psi Cyl 4 - 137psi Cyl 5 - 157psi Cyl 6 - 142psi   Cylinder 5 and 6 having the most carbon on them.
    • Who did you have do the installation? I actually know someone who is VERY familiar with the AVS gear. The main point of contact though would be your installer.   Where are you based in NZ?
