Title: Upgrading spring plates (swing axle) Post by: runningmonkey on November 13, 2017, 17:34:09 pm So iv just removed my gearbox in the drag bug and Iv notices that the spring plates are ever so slightly twisted. Its not by much, but you can tell by just looking at the spring plate,
I am thinking of replacing the pair for an upgraded set but I can't seem to find any standard upgraded ones there either all lowered or adjustable, can some one point me in the right direction of who sell them in the UK? Cheers in advance Title: Re: Upgrading spring plates (swing axle) Post by: Garrick Clark on November 13, 2017, 17:59:30 pm Not sure were you'd get them from. I have a pair on mine, came with the car. Proper heavy duty .Well worth buying. I'd be asking on the samba as I think you'd have to get them from the US.

Keep an eye on the classifieds on the US site , I got mine from there nos at a good price. You've an oval ? https://www.thesamba.com/vw/classifieds/detail.php?id=2011904 Title: Re: Upgrading spring plates (swing axle) Post by: runningmonkey on November 14, 2017, 11:10:44 am Yeah oval, full weight
My new engine going to be around 300 BHP, most of my rear suspension has been upgraded but still running stock spring plates. It doesn't seem to a upgrade that folks do over here in the UK do, but seems common practice in the states?? Are they worth upgrading? get confused now ??? ??? ???

they look very good quality, no one was selling these in the UK so had to get them shipped over Title: Re: Upgrading spring plates (swing axle) Post by: Dalland on November 15, 2017, 14:11:30 pm Can't understand why you should change out the spring plate because it is twisted, it is what it is designed to do...

I thought lots of companies would make up-rated ones and it would be an easy upgrade.

I thought lots of companies would make up-rated ones and it would be an easy upgrade. I can't tell you what is needed for 300+ hp, but keep in mind that many aftermarket spring plates are not "spring steel" as the oem are. And to increase the thickness doesn't make it much stronger for the kind of force it has to handle because of the direction of the force. I believe you will be well suited with a nice set of oem spring plates and good pom(delrin) og urethan bushings.

The ones that CB performance make state there made from spring steel, so designed to twist but are stronger. Quote Racing spring plates are manufactured from spring steel, full heat treated and cadmium plated. The spring plates are .250" thick (twice as that of stock units) and are a must for off-road racing. You can convert yours to the short 21 3/4" length torsion bars for tire clearance. The hubs are broached an extra .500" to compliment the extra length of the racing torsion bar serrations. They will also fit standard torsion bars. Racing spring plates are available to fit both swing axle and IRS rear suspensions. Tho I think you maybe right, if I can't find any suitable replacement sets I may just get some oem ones.

As they are bolted solidly to the axle and the torsion bar (rubber bushing ignored) and the axle prescribes an arc when it moves then if they dont 'twist' the suspension will bind up. I have no clue what a thicker plate will do wrt suspension rates but it will affect them to some degree as it will try to resist the twist more. Cheers Marc |
