I'm currently running a non hicas S13 rear cradle, with cheap aftermarket toe and camber arms, R33 GTR hubs, R32 GTR axles and diff.

I have a R32 GTR cradle laying about and since i'm swapping the GTR diff for another one i have anyways (existing one is worn out and getting noisy) and my cheap toe rods are starting to flog out i'm wondering if i might as well just swap to the GTR cradle.

I've not looked closely at the cradle yet however it appears pretty similar in all areas except for how the diff mounts and that it has HICAS.

Perhaps the rear suspension mountings differ as well but i could get around that by using the S13 outers of course (assuming that all the arms are the same)

If i fit the GTR cradle i'll make a lock bar for the HICAS of course and since it'll be using OEM quality tie rods i'll have eliminated my cheapo toe rod problem.

I'm hoping i can fit the S13 castor arms to the GTR cradle to.

Does anyone know exactly which components of the suspension are different and if i could make a mix/match setup using the bits i have.

Also is the geometry of the GTR cradle any different to the S13 one?

I'm pretty certain that mounting wise the GTR cradle is a drop in swap.

If no one knows then i'll have to start actually trying it out.

a gtr diff wont fit into a s13 cradle as the only have 2 bolts on the back of the diff

a r32gtst diff will fit

    • So, the other thing I've sorted is a baseline dyno run up at Unigroup's new location. The auto trans was a little unco-operative by both shifting down when the throttle was floored on the dyno (so Mark had to ramp it up more slowly than in a manual) and also by shifting up at 6,000 even in sports mode instead of the indicated redline of 7,000 Still, on a hot day it made 240rwkw at 16psi which seems about right for 300kw (400hp) through an auto at the wheels.  The shape of the curve is not quite right because it was not full throttle to about 4,500 to stop it kicking down, but until I can get a tune on the auto trans control this was the best we could do.....full boost will be well below 5,000 once that is sorted, I'll get some data logs when I can to confirm For comparison, the R32 made 255 at 12psi (at 4,500) on the same dyno with tune, n1 turbos, cam gears, big exhaust but otherwise all standard so the v37 is likely a little better out of the box. One thing that is very clear is that the standard water to air intercoolers are not up to sustained use at full throttle in warm ambient temps. After about 5 runs (so only a few minutes full throttle), it was pulling boost and timing and dropping 10-15% power. Unfortunately I didn't get that printout and the Unigroup guys are away at the moment, will try and get hold of it on their return. So, looks like a healthy engine to start modifying and the only real area of concern is the w2a heat exchangers which the aftermarket has plenty of solutions for    
    • I maintain it actually looked really nice in person. So much so that I thought "No, this is illegal" but there it was, clear as day. I think we can easily call the wing and wheels/height to be transformative. Not saying it's better than the GR Whatever, or the 86, or the WRX STI or anything of that sort (the internet says it all bolts up so you can buy best of all worlds?) but it's still at least a thing and not nearly AS bad as people say.
    • That's less offensive than the previous gen.....except for all that ugly black tupperware around the edges. Blerck!
    • I leant out the window recently and took a picture of this new WRX. It looked real damn fine in person. It's faster around a track (stock) than a (stock) GR Yaris. It's much more practical despite being heavier. It's significantly cheaper. This gen tunes really well, much better than others. .... I think they're probably a lot better than people expect.
    • WRXs are a pure pleb boring car these days. You need to get an STI to even get close to what a WRX used to be.
