Jason Moyle Racing

Fantastic- there you go - 4" 

Have raised it a touch since then but thats as good an estimate as we will get.

Interesting thing about the ibiza beam is that the bushes are properly fore/aft, unlike some of those I have seen from a golf which tend not to point exactly for/aft, with a bit of 'toe in' so to speak. No idea how this might affect the beam in movement.

This might be of interest also, Mk3 golf VR vs late (large bush) Mk2 Ibiza beams









The golf has longer 'arms', the axle center is higher on the ibiza, the golf beam is wider overall, the bushes/fixing brackets are totally different (hence why it is not already on my car.....)

How will the car react with raised or lowered rear RCs? On rear beam cars like ours.

Reading about the subject the front to rear RC relationship is ment to mainly affect feel, I have not ever had the chance to alter and test so don't have any first hand experiance myself. Supposedly, Pug 205's had a lower rear RC compared to the front and this made it 'twitchy' in turn in and corners. Cars with higher rear RC are meant to be nicer to turn in... Which setup up makes you faster around a corner seems difficult to find data for.

I think they have potential.

The CV splines look like they might suit the Gemini shafts I have with a bit of parts bin shopping, Audi S2 spec Robt tells me.

The struts suit a number of more modern race cars dampers and I think there will be a few that will suit, I have some plans and my eye on some nice kit from Seat Sport .

The geometry can be adapted, the wishbones I have are fully adjustable and coupled with the adjustable top mounts will give plenty of options.

Probably not a project for this season but will start getting parts and plans together.

This season's mods are a very special beam and rear suspension parts. More to follow.......

The inspiration for the billet upright I'm designing came from Goodwood Festival of speed earlier in the year. I saw this simple design (image below) which had parts bolted onto it, it got me thinking, it made me realise an upright could be produced cheaply. I did not start designing until later on in the year after a trip to Ferrari World in Abu Dhabi, there, I had a go at the pits stop challenge, where you take of and replace a wheel from an F1 car as quickly as possible, on this mock F1 car the hub was interesting and jolted me to start designing.



Modern VAG cars use bolt in front hubs and wheel bearing carriers with aluminium uprights. I like this idea for many reasons, the main being that no geometry has to be altered to change the bearing (which would be a quick job), the steel bearing carrier is strong enough to hold the bearing but uses minimal heavy steel material. The bulk of the upright shape is then aluminium. I looked at using the std bearings and hubs from other VAG cars like the example below, the main issue was that the outer CV would not fit, the only solution would have been to replace the CV and use custom drive shafts, this would push up the cost of the project.



My solution to this was to use the mk2 golf steel upright, but turn it down so that it is just a bearing carrier, weld on a flange and it's ready to be bolted on. The beauty of this is that the std wheels, CVs and drivesafts will all fit, I have a pair of old 8v hubs sitting in the loft ready to test and it might be argued in Motorsport that you are using the std upright, it is just modified with an elaborate lower ball joint spacer and brake spacer all in one.

I set about cutting up a hub and turning it on the lathe, the wood is a quick laser cut template for what the flange may look like. This was really proof of concept, if this was possible it was game on. 

Awesome work Tom 

I think I may have to have a think about doing something similar for my Mk1 racer to get rid of the horrible ball joint extenders I'm currently planning on using that I have some serious reservations about!

Very similar effect to the spacers I had laser cut Tom to mount an early Mk2 balljoint to a Mk1 wishbone....
