Hi guys, I got 9.5" width wheels at the back for my S15, in order to pass the engineering certificate, I need to strengten the whole back end of my car with car that has standard 7.5" instead of 6.5" (on the S15) so my option is the GTR end, diff, bearing etc whatever controls the end of the rear wheels, now my question is where can I source one out? and who should I talk to get the work done?

Please don't tell me to swap the wheels to 8.5", coz I already bought the wheels and took me 1.5 months to get them :)

Thanks for the help in advance

i have a rb26/30 in my s15 and i use a complete gtr rear end, the whole thing bolts into the s15 chassis....

if you decide to use this, i think the final drive (4.11:1) will be too tall for your 6 speed as the s15 comes with 3.7:1.. this is the only thing against you... and tailshaft will be different

otherwise, the complele rear end shits all over the s15 ass end, the gtr uses a mechanical lsd, it has alloy stub axles, and thicker drive shafts...

good piece of gear compared to the s series chassis cars...

and you will never break it

This post will be no help to you whatsoever but can I just confirm what I see here? An engineer wants you to strengthen your rear end because you have wider wheels than standard? What a f**king joke. Are you going to be driving around on Mickey Thompsons all day every day? And you can bet this guy takes himself totally seriously too.

Ok here's something semi useful. I have an R32 GTR rear end in my R34 GTT and it's a great piece of gear. Paid $700 for the whole kit and kaboodle and it's tough as nails. Really tough nails that is.

I know I know. I just hate people who blindly follow rules without question.

Think for yourself

Question authority

Throughout human history, as our species has faced the frightening,

terrorizing fact that we do not know who we are, or where we are going in

this ocean of chaos, it has been the authorities, the political, the

religious, the educational authorities who attempted to comfort us by

giving us order, rules, regulations, informing, forming in our minds their

view of reality. To think for yourself you must question authority and

learn how to put yourself in a state of vulnerable, open-mindedness;

chaotic, confused, vulnerability to inform yourself.

Think for yourself.

Question authority.

nah, only r32

ummm in my experience R34 is easier than R32.....

S13-R32 str8 swap

S15-R33/R34 st8 swap

combining the two ie R32 into s15 streches the bushes and usually ends in a skewing cradle (crabbing car) after awhile. We run R34 GTR in the S13.

and fitting the GT-r cradle wont fix your over tracked rear end..... as i assume they are worried about the track change more than anything. If you truly are being hassled for axle loading then yes it may be easier to get through with a GTR rear due to the higher factory load rating.

remmebr though you will also need new rear coil over bases as the lower mount is fork not eye.

Hi peeps, I am in a similar situation, I have an S15 that I am currently doing an RB26DETT swap in and at the same time I am looking at swapping the GTR 32 rear end in as I got everything as a package. I want to know if I were to unbolt the entire Differential, axles, and brake setup minus the spindle from the R32 GTR rear sub-chassis would it bolt directly onto the S15 rear sub-chassis. I will be using the S15 spindle of course and using all my S15 arms and whatnot. Can someone that has done this let me know, I have the entire R32 rear end but I have already bought my S15 Cusco coilovers and don't wanna have to use a combination setup.

    • Block bump. $400. As above cyl 6 needs bore or sleeve.
    • I would think making the argument that the travel is limited by a spring flexing against a spring perch as "the same method". Later on in the document they do state that the spring can't bind on full bump travel and cannot come loose in full rebound travel as well. (which is all very sensible). The laws are actually pretty sensible and reasonable. It's just that the people who enforce and check them don't actually read them or know them accurately. "Oh, coilovers? Instant fail mate. Don't even need to look at it." - Guy who will be instantly reported by me. There is probably merit to people who do get defected for height also get defected for the suspension in that state that allows it. I did never consider the people who are complaining about coilovers being picked on are also running around at 50mm off the floor.
    • I think given SAU's knowledge of E85 we can strongly conclude that 10% ethanol in almost any situation is entirely fine. Almost all of the myths against E85 were overblown, let alone E10.
    • From your link See bold text, is this referring to damper settings, if so that may a issue for "some" inspectors, I cannot see aftermarket coilovers having the evidence that "must be available that its functional performance is equivalent to the original" Maybe just remove the adjustment knows and hope for the best???? Meh 5.2 Suspension travel In all instances, modifications to a vehicle’s suspension must ensure the integrity of the system and not compromise the ride quality. At least two thirds of the original suspension travel should be maintained in both directions (rebound (i.e. extension) and bump (i.e. compression)), and rebound must be limited by the same method used by the vehicle manufacturer or if this is not practicable due to the nature of the modification, an equivalent method. If an alternative method is used, evidence must be available that its functional performance is equivalent to the original.
    • They actually don't - They adhere to VSB14 rules just like Victoria. The rules are against CABIN adjustable height, and it quite clearly states that the height has to be within parameters. I asked the VASS engineer to confirm this when I got my car engineered and they refused to engineer the coilovers because they didn't meet the requirements for requiring engineering. (mine are height adjustable.) People "Not wanting to bother" with "Actually reading/knowing/adhering to the rules" should result in fines and immediately losing the ability to issue blue slips and/or RWC's in Vic.
