Anyone have a strong preference between Weiltmiester or Elephant for rear spring plates?

I’m wanting to fit adjustable plates so I can set my rear ride heights. Any recommendations?

Many thanks. Gary

I bought a set of these for our hillclimb car a couple of years ago -
https://www.ebay.co.uk/itm/Porsche-911- ... OSw3xJVVf6~

I had to get a pair of bushes made to suit the larger diameter shaft made, as the rubber ones supplied were totally wrong, and I wanted solid bushes at any rate, but they were quite simple to fit, and haven't been any problem since in more than 2 years of competition.

Cheers,

I bought this.....it reduces set up but over an hour as makes it all much easier https://www.elephantracing.com/porsche/ ... t-for-911/

That looks a nice simple piece of kit, Raymond. I haven't seen it before.

On advice of the car builder, he says don't fit the adjustable rear spring plates as they will fowl the rear tyre. I don't have the clearance. If I then use a spacer, I'm going to have the tyre outboard of the (narrow body) rear fender. I'm therefore stuck with a ride height which is slightly too high, but I don't have the fine adjustment to lower it (other than to index the torsion bar).

There you go... learn something every day. I could go down the path of widening the rear arches in the normal way - but will lose the look of the narrow body. I'm told that many original STs were narrow body at the start of the their lives, only to be modified down the road. Anyone comment?

I run rears with an extra 1" inset, like the 7R Fuchs, with 9" rims and 10" Avon slicks under SC arches, and have no fouling problems.

To fit the adjustable spring plates you will have to re-index/set up anyways so why not buy the ER adjuster, re index and set to highest setting and work down from there. Use the ER adjuster for camber. i am a little surprised that the arms would foul tyre before hitting inner wing first! I would check with Steve Winter at Jaz?

My 73T has SC 2 piece Spring arms, no probs at all with the inside Clearences.

I have the ER ones on a widebody. Saves a LOT of time setting the car up and is a cleverly made piece of kit. However, the quick change plates are not FIA App K compliant if case you want to race the car in historics and/or want a HTP

Dumb question alert!

Is there anything to stop the wheel end of the arm lifting off the adjuster screw/bolt? From what I can see its 100% reliant on the wheel moving under the power of the "spring", and the spring providing some pressure between the adjuster and the plate throughout the range of movement of the damper..

Just wondering if there's ever any "rattle" if the wheel out accelerates the torsion bar, or if there's some hidden lock feature that I've not noticed (ie a top and bottom adjuster screw clamping the plate in both directions)

I am planning on using Sway-Away adjustable spring plates, they look just like the ones on ebay. Again they need their own bushes as they are a slightly different diameter. Smallspeed, I think you are looking at them upside down. The screw pushes up on the torsion bar part as the wheel rises and cannot fall off it's stop as the torsion bar cover plate holds the whole lot together. As the wheel falls, it is damped, so the torsion bar will always be pushing down!

My ones have a securing bolt which clamps the two plates together once the height is adjusted.
I’ll post a photo this evening - if I remember!

Stock 911 2.7 (74?) onwards to 1989 set-up below.
Slacken both bolts which are eccentric specials.
Set the geo with these finger tight or more, when done tighten.
You need a very thin large open end spanner.
The two pieces are thus firmly 'together' and will act as one piece.

Ah ok that makes sense..
Without the locking bolts my thinking was you’re dependant on your springs and dampers keeping up with wheel movement

As others have said, because of the combined effects of springing, damping and inertia, the adjuster doesn't chatter, but the clamping bolt between the two parts provides belt and braces.
Ride height adjustment is simple with the adjusting bolt and lock nut, and the adjuster doesn't come anywhere near my tyres. It doesn't protrude much more than the securing nuts between the spring plate and suspension arm in any case.

Cheers!
