  • K24R Offset Solid Top Mounts

    I've been designing these in the background for some time and am at the stage where I'm looking at numbers for a first batch.

    These are solidly moutned top mounts so are harsher than the rubber items but cannot be bettered for solid location of the strut (with stock suspension hardware anyway).

    They are offset by 7.5mm, giving 0.75degrees more castor or camber (useful for lowered vehicles as it reduces the effect of the wishbone arc inducing negative camber). They can also be set to give any proportion of camber and castor correction in the rotation available.

    I have specced silly oversized bearings for these with the aim of making them bullet-proof, the bearings are replaceable from a stock size and cost about £70 for the pair from the supplier!

    Price is looking at about £225 a pair, delivered, but can be specified with different bearings to save approx. £25 (I'lll assess both types to see how they're affected.

    I am also working on a rear strut brace solution that ties in with these at the rear of a coupe / 90q, cost is looking like £350 at a guess (for top mounts, brackets and bar) but this is speculatitve at the moment as it's still on the drawing board. Not cheap I grant you but no welding, cutting or bolt holes in the rear strut towers and it will not encroach into the rear load space anywhere near as much as current solutions. It will also be high quality anodised aluminium billet, CNC machined and the strut bar will be designed to be chromed at an extra cost if required (stock finish will be powdercoat).

    I will be getting a test batch of these made and will run them for a bit to test, I also have a few beta testers lined up to get a more thorough test program sorted.

    Post below if you're interested.

    i got promounts at the moment. pretty interested here andy. sounds good.

    are these front and rear. will this reduce rear flex from this god awful chassis.

      Interested.

      Running on standard mounts at the moment after a garage attempted to fit my new solid ones with what appears to have been a poorly calibrated hammer and chisel.

        Without sounding like a knob................. Would it be possible to see your design andy (can be via pm)... I've designed custom one offs for my golf which bambridge is quoting me happy for, mine are solid mount but with weld in adjustable top plates to allow 20mm adjustability (+-).

          Andy, whats the difference between these and yours?

          * Option built in 1 deg negative camber. *

            Not sure how they do the camber as they look concentric, must be a different housing for that, it requires around 10mm offset, something that I found to be difficult due to the sze of the bearing and wanting to retain structure at the edges. I think my bearings are larger, they quote a 17mm bearing, mine are 25mm as I wanted to avoid the problems others have experienced with under speccified bearings so found the bearing that was right for the job before I did a feasibility study on the mount design.

            I am already aware that concentric solid mounts exist from several manufacturers and that Promounts and 034 offer a range of upgrades so there was no point in doing anything similar as I'm doing small batch, high quality products rather than a coimmercially viable product. Eccentric mounts are available but are a small fortune from the US, 2Bennet, strangely enough, they look rather like mine but I didn't see them till after I'd pretty much finished the design on mine, have seen other similar designs for Golfs etc. so must just be an obvious solution.

            No worries, always happy to discuss designs (as some will testify ), means I get it spot on, criticism and questions are essential in the design process to ensure that you try and design out and problems before they are made!

            I would be very interested in seeing what you have done, email me at the address in my sig , my design is shown in the 'projekt kamber' thread, always good to see other solutions to the same problem, even if the Golf isn't identical. One of my requirements was to ensure that there was no modification required to the strut tops, no cutting, welding etc. If I was willing to do this then I could have made them adjustable by up to 25mm or thereabouts. The Audi strut towers are really limited for space and thus what can be achieved, unless you space the bearing down a lot and then use the space in the turret (to avoid strut tower modification). All the hardware is beefy as hell too, don't forget that the front axle on an S2 takes more load than the weight of any mk2 GTI so everything has to be up to the job, the bearings used are much larger and more expensive than say those used on a rally mk.2 Escort.

              The aim is to use the same design front and rear. Up front they can be used to give camber, castor or both, at the rear they can be used with a brace bar and improve camber change on the macpherson strut design, it's a small change but they all add up.

                Rear strut brace is designed and is off for quote also. Should be able to price it all up then. Using the offset bushes means that the rear strut tops are bought inboard a little and makes it a bolt-on solution. It also means that, by sharing components, I can get more parts made at once

                    Not really, just been pricing them up and have a couple of tweaks to make. Then it's a matter of sinking some £££ into them

                        Im holding off on the purchace of top mounts to see the outcome of thease first..... looks promising
                        Probably the longet S2 project in history EVER!

                          OK, well if there are bigger numbers interested then that's good If people want to pre-order then I'll do something on the price. I'll have a good look at these next week and get something sorted. I should be able to sort a rear strut brace for coupes too, hoping that the whole lot will be a nice setup.
