Yup, glad you asked. The second version of the bushes should be with me next week and we have a customer's track car in the shop which is likely to be the testmule for them. As soon as TT reports back positively we can bring them to market. In the end we decided to incorporate a self-lubricating bearing into the design as an all-poly bush would probably suffer from premature wear due to the loadings. Stage 2 will be to experiment with bush stiffness once the design has been proven.

The prototype bushes have just been fitted to Tony Taylor's 964 trackday special, in fact the car is still on the ramp having it's brakes serviced whilst we are there. We decided to test the harder track version of the bush first, hopefully TT will have a trackday soon so that he can report back on how they feel and drive in comparison with standard. I'll have prices in a few days and in the mean time will try to work out a special "bulk buy" deal for fellow Rennlisters, more soon.

Colin,
Are we in Prepared G restricted from replacing the bushings with monoballs. That was going to be my winter project.
I was interpreting this from the PCA rulebook as allowable.
J. Suspension bushing materials are free. Replacement of suspension bushings cannot alter the suspension
geometry of the vehicle.

Not long to wait lads. The bushes have now been fitted to Tony Taylor's 964C2 and we are just waiting on a new set of wheel spacers to be fitted so that he can track test the upgrade. Hopefully TT will be post a favourable report in the next week or two.

OK guys, the final costings have come through so here is the deal on offer:
The price of these bushes is £195 per car set (plus VAT, shipping, etc.), however assuming that we can put together a group buy of 20 car sets I can reduce that to a one-off price of £170 per set. Production is going to take 2-3 weeks from order. If the current version of the bush proves too hard for road use we will introduce a medium version later on, but please keep in mind that I won't be able to exchange the hard units for medium if they have been used.
I'll get Peter in our office to co-ordinate the orders and work out the postage costs to Europe and the US, however what might make sense for convenience and cost is to bulk ship a batch to the 'states and distribute them from one source.
Please understand that these bushes have not been thoroughly tested yet so they have to be sold as a non-warrantied racing part "not for highway use", although looking at them it defies me to see how we could have a potential problem.
