    Few mods recently, I've upgraded my rear ARB from an Astra mk2 15mm to a Saab 93 uprated 22mm item. I intend on doing some back to back tests to see how it behaves.





    Cadwell Park yesterday. Weather was atrocious, couldn't even see where you were going in the morning. Lots of red flags and nasty crashes.

    Will upload a few official pics when they come through, but only snapped one to show how nice a mk2 front end looks:



    Bit of a lap video but pretty uneventful really:

    Little upgrade to test out, Tranx 45/45 heavy preload plate diff to replace the ATB. It came out of Houses Quaife sequential when he upgraded to a Gripper, so I'll get it installed and see how I get on with it.

    I like my tranX plated. The car likes the full throttle turns, without that is understeering, but with is a little oversteering.

    Be interesting to see what it performs like with the 45 ramp angle on de- acceleration. I’ve always ran 45/90 on my tarmac rally car as I never wanted the diff to work on de acceleration/braking

    Got a 45/60 in my hillclimb car and really like it compared to a 90, can really feel the diff fighting on decel, 45 will be interesting but the high preload should subdue it a little
    If Carlsberg did Motor clubs, then IDMC would probably be the best motor club in the world.

    I'm running 45/60 heavy pre load in mine and love it.

    The 45/45 was a compromise for Iain as that was what I specified originally from Quaife, we'll see how he gets on with it

    A few more mods before Snetterton.

    This style coilpack bracket was nice, but made from stainless and far too brittle which led to it cracking:



    I've sourced an original C20XE coilpack bracket which mounds on 3 bolts on the head and is made from 5(ish)mm pressed metal. Just needs redrilling for the Ecotec coilpack:



    No water thermostat is fine in summer, but I saw temps in the 60s at Cadwell which will start adding more fuel. So I've fitted an 82C thermostat (LMF) and alloy radiator (TXAutosport).





    Going to redesign the oil cooler top brackets too, I think.



    Diff was fitted a few days prior to Snet, new bearings, seals, swapped over crownwheel. Job is a pain upside down, should have taken the box out.

    Snetterton 01/11/2019

    Wet day, couldn't really test the diff out was just holding on and battling no grip.

    House brought his non-road-legal-wets which he hates for some reason, so we swapped some wheels and both ran Rainsports up front which worked pretty well for us.

    Had a surprise visit from Rich off here just as the millionth red flag in the afternoon ended the day, so nice to meet you sir.





    Couple of pro shots from the day:
