They have remote valving too that changes the response based on pitch vs roll, as well as different stiffness for car pitch under braking vs pitch from a jump landing, etc.
 Not sure what's gone on with the dash picture:



Also just finished making a prototype of the new fiddle brakes:

Working on the mapping this week so the next video should have a bit more noise  :D

Right, I've got it settled down a bit and responding to the throttle properly now - it needs some more fine tuning to really perk up the response but it's just on the safe side until it goes on a dyno.

I'll get some video next week.

Bad news is we can't use those rear CV/Aero boots - the driveshafts hit the casing - that's what you get for not checking things with the boots on!

Good news, found some boots that work.
Bad news. Might have cut the front beam, arms and uprights off the car... ;-)(-;

Good news, new ones are being made, already mocked up and ready to go:

Yes, took a lot of planning and mockups since we're so tight on space up front, making sure the shocks/steering links, etc, clear everything and we can still get enough steering lock.

On the upside ditching the link pins and kingpins for spherical bearings mean that there's no longer any play required in anything like there is to allow linkpins to rotate, etc, so everything can be torqued up tight. Which means no geometery changes from play or as the clearances change through wear.

 Took the opportunity at the same time to revise the front geometery a little more, reducing some of the castor gain, removed some of the mechanical trail and corrected a lot of the scrub offset issues the stock setup has.

Been chasing down an intermittent, annoying issue for the past month or so where the car would only fire up 50 percent of the time - and sometimes would cut out for no apparent reason, eventually traced it to a dicky cam sensor and some split wiring on the only original part of the cars loom we kept - the coil connectors, doh. Anyway, after taking allsorts off finally found them, repaired 'em and turned the key, boring video but god was I happy!

Sound is a bit funky as the phone clips hard on the audio that close and the exhaust's blowing from the elbow there 'cause it just got slapped on.

Why is it that some people have the facilities\equipment and the skills for this sort of thing and I don`t  ?  :'( :'(

Equipment is expensive so you need to be using it a lot to make it worthwhile and you may need three phase power.

We started making this in a shed we'd made out of some old tin sheeting and some gravel raked over from the floor, an angle grinder and 30 year old MIG set that was my grandads - and it stayed that way really up until the latest engine change.


Yes, we have room and some fancier gear now, but they're investments for work as much as anything - even this shed we built ourselves from shipping containers - nothing will stop you doing this even in a garage with hand tools and odds and sods, you just need to get into it  ;-)up
 Hell, my daily driver is getting a complete engine and gearbox change in the middle of the street at the minute!


Found another problem that was giving the intermittent weird noises and cutting the engine out - alternator is goosed and it was tripping the ECU, took it off and it's running like a dream now. I was going to get some video but it was 11pm by the time I was done, I've got hospital tommorow but maybe some better engine video Thursday  :)

Aghhh Keith...   You have mentioned what was the bane of my working life,,,,,  "3 Phase electrics".   Had to keep huge axial fan motors, pumps etc running. Many originating from the 60`s and still in use. Almost a daily occurrance for one of the 3 phases to go down on one bit of kit or other.. Huge tubular fuses and contactors that clacked in and out with the contacts often fusing together with the heat.  Don`t think I want to see any more. I can still smell the huge cabinet DB`s when I think about them.   ;D
