Thanks for sharing. That's a great video! My buddy is doing the same thing on his build (S chassis struts and towers). He's building an S14 with billet RB30 shooting for 2000whp... a race car with a TH400 just like this video. For a road car I just couldn't go this route as the strut has to be almost vertical and the caster is not going to pivot correctly (let alone camber gain). You think the R32 frontend is bad, wait till you put a MacPherson strut on without modeling it all in Solidworks to check geometry. I'm not saying it's a bad way to do it but I'd be really curious to see how it affects the geometry.

Had I known the diff between R32 and R33 suspension I would have R33 suspension. That ship has sailed so I'm doing my best to replicate a drop spindle without spending $4k on a Billet one.

OEM suspension starts to bind as soon as the car gets away from stock height. I locked in the caster and camber before cutting off the kingpin. I then let the upright down in a natural (unbound) state before re-attaching it. Now it moves freely in bump and droop relative to the new ride height. My plan is to add GKTech arms before the car is finished so I can dial camber and caster further. It will be fine. This isn't rocket science. Caster looks good, camber is good, upper arm doesn't cause crazy gain and it is now closer to the stock angle and bump steer checks out. Send it.

The frontend wouldn't go low enough because the coilover was max low and the upper control arm would collapse into itself and potentially bottom out in the strut tower. I made a brace and cut off the kingpin and then moved the upright down 1.25" and welded. i still have to finish but this gives an idea. Now I can have a normal 3.25" of shock travel and things aren't binding. I'm also dropping the lower arm and tie rod 1.25".

Motor and body mockup. Wheel fitment and ride height not set. Last pic shows front ride height after modifying the front uprights to make a 1.25" drop spindle.

Here's Logans Silvia with R32 Drivetrain, mine will be slightly lower (more angle). He was constantly blowing the RH axles at around 16deg. I want to avoid this.

Is anyone running these axles? R32, R33, R34 GTR front Axles. shafts itself rated 950hp. Suit all RB26 engines Croydon, Melbourne, Victoria Would be nice to pay half the cost of Driveshaft Shop Axles. I'm building an AWD S13 Coupe that is very low ride height (high cv angle) compared to stock R32. Has an RB30 with appx 600whp. Just looking for feedback.

I just found these also... Kiwi CNC Ltd Nissan R32/33/34 GTR Motorsport Uprights

That's a nice piece. I'll look into it.

I should have specified. R32 GTR Suspension.

Those are RWD only unfortunately. I think at this point I may switch my plan from building the RB30 to building another motor. I have an RB25 bock/head and RB26 crank/rod/pistons. If I build that motor, I can raise the cross member up 1" which helps a ton with ground clearance and then if I modify the knuckle arm at the top I can get more bump without causing the geo to be all whacked.

I'm really looking for another 0.5"-1" of bump for safety reasons. Crossmember will be about 1" off the ground at that point so there's that.. That's the downside of fitting an RB30 in a S13..

Moving the holes down also allows me to shave material off of the top. This way it can travel farther without risk of hitting the strut tower up top. I might just buy another upright and start playing with different positions and check how the suspension reacts. For now, I'll just get the GKTech FUCA's like you suggested. I was shocked the first time I cycled the suspension and found it had so much bind up top. I initially thought I got a dimension wrong for strut tower/crossmember placement... Here's my Instagram if anyone wants to follow along... 風水 (@feng_shui_garage) • Instagram photos and videos

Has anyone moved the R32 FUCA outer pivot point down to allow more compression? It seems like the R32 front suspension is not happy about going low... I just swapped R32 strut towers (full GTR drivetrain, RB25/30) into my S13 and she sits a little high. I've also been looking for better control arms that don't bind but I only see bad feedback about what's on the market. Images show full compression (on jack) and then ride height with not much bump (1.5" maybe). Knowing what I know now I would have gone R33 frontend but that ship has sailed. Looking to make the best out of the R32 bits.
