935 RSR Spring Plates

pete917 · 09-25-2008, 07:26 AM

Im going to RSR valved and sprung coilovers. I am also going to fit 935 RSR Spring PLates like these:

These are from rebelracingproducts.

Im sure there are others out there. Does anyone have experience of these and are there better quality ones.

Thanks Guys

Looks pretty high quality to me.
You appear to have 3 different positions (holes) for the spring plate joint to mount to. Is this for changing suspension geometry for anti lift and camber curves?

So this just eliminates the standard bushing way for the spring plate to rotate around the torsion bar centre line. It then provides a very simple toe adjustment along the long axis. Camber adjustment remains as standard. I also think it meansd camber and toe are no longer related and can be adjusted seperately and more easily.

Clint (rebel racing owner) has done very high quality work for me and I've used various products from Rebel Racing as have several other friends.

I haven't seen these products in person, but would expect them to be very high quality. He's a degreed mechanical engineer and machinist and son to a veteran Porsche shop owner and restorer of 30 years.

I endorse Clint's work and would recommend it even without direct experience with the given product.

If you are comparing to other 935 style spring plates, I cannot offer insight.

ERP- Eisenlohr Racing Products also makes these.

A friend (cstreit here on Pelican) runs these on his 1970 911S 3.3L GTS4 race car and has had great success with them.

ERP has made them for a while now. . . . .Just from looking at both products, the Rebel racing plates look better engineered, stronger than ERP.

Looks like Clint's done it again! I've got some of his parts and they are top notch.

I have run the ERP versions and the TRG ones. Both of those worked the same.

These new ones look similar but do have an extra pickup point option over the other two.

My last issue to find out is if the rose joint is a sealed type or it will wear out very quickly with grit and dust ingress. I am going to ask if its a PTFE coated type or plain steel. Apart from that I hope to buy a pair soon.

Does anyone know the answer to this one???

Why not email the manufacturer and ask?

I know the other 935 spring plate come with Teflon lined spherical ends..I'd bet these do also...

Sealed no.

already sent the email. Wuill let you all know what the answer is.....

I just received a reply to my email.

"The rose joint is made from alloy steel (cromoly) and has a teflon (ptfe) impregnated Kevlar weave liner. This is due to the fact that rose joints strictly lined with ptfe have the tendency to suffer from flat spots in high load or impact applications. The Kevlar in our joint provides the impact protection and the ptfe is a superior self-lubricating asset."

The units are not sealed however, so the supplier recommends using a pair of rubber weather seals that are readily availble.

So, I am going to order a set of these spring plates plus weather seals. I'll post some pics when they are on the car.
