PBM S13 coilover help, tech questions

[tubedae86]

Im looking to get some for my custom chassis that utilizes some nissan spindles. But before i decide i need a couple measurements that PBM can not supply at this time. Anyone that has a pair off vehicle willing to take a couple measurements for me?

i need the max and minimum lengths, threaded all the way up, and all the way down

Front: Measured from bottom of camber plate to the center of the top bolt hole.

Rear: Bottom of pillow ball plate to center of the bottom coilover mount (part that bolts to knuckle).

SO this should mean two measurements per front and two per rear.

Thanks, Matt

I'll share some of my numbers with you, but you should totally ask Dan at PSM for some more accurate numbers. I only measured the fronts, sorry.

Springs are about 178mm. Bottom bracket is a 140mm. Bolt-to-bolt of the bottom bracket is 60mm. On the lowest setting from the bottom of the camber plate to the center of the top bolt of the bottom bracket is about 225mm. That's with both collars removed and brackets flipped. The damper length from the bottom of the camber plate to the bottom of the damper is about 380mm.

These are with the older models with bottom brackets flipped. You don't have to flip the '09 models. I have the '08 models, bottom brackets flipped, both collars removed, 215/45/17 tires and the bottom of my fender is just a hair above 23" from the ground. And my fenders aren't even on right. Really though ask dan.

also, happen to have the maximum length from bottom of camber plate to top bolt hole in the front? thanks again, Matt

I don't have any spanner wrenches to get any exact measurements but it's not very high. On the '08 models the bottom bracket isn't threaded all the way through, idk about the '09 models. That's why I included the damper length length instead. An estimated guess is something like 465mm. That should put the bottom of the damper in between the 2 front bolts. The dampers are pretty short compared to other coilovers like stance and KTS.

Just took some quick measurements of the rears. The bottom mounts aren't threaded all the way to the top so maximum height is limited. Bottom bracket length is about 185mm from the top of the mount to the center of the knuckle mount. About 100mm of thread. Springs are about 180mm, like the front. Damper length I believe is the same as front. 578mm from the ground to the top of the fender arch with 215/45/17 tires, about 17mm of thread left. I believe you can thread the bottom bracket up under the spring without having to droop. With the damper about 1/4 from the top total length from the bottom of the pillow ball mount to the center of the knuckle mounting point is about 530mm. Lowest would be about 410mm.

I hope this makes sense. I edited some lengths on previous posts.
