Thanks for the welcome guys.
I am running in (rather than competing in) the HSA Championship this year. I fully expect to get mullered in the Modified class with my humble 310Bhp but I intend to use this year as a learning event and next year decide whether to bring the car up to a competitive spec or try something else. That and most of the stripping out is already done so the prospect of spending money making the car heavier doesn't appeal. Thanks for the baffled sump tip though. I'll look into it.
Good point on keeping fifth gear. I am pulling 130 at the bottom of the Hangar straight at the moment so I probably don't want to lose too much top end. Perhaps a Cusco centre diif to get the some rear bias would do the job? North Weald is pretty viable from where I am so I may chance my arm later in the season.
As for petrol consumption; on my last trackday I got through 90l over 120miles. I make that around 7 mpg! It is a little better on a run. It just doesn't tend to go on one.

That's nearer 6 mpg 
Think I'd be checking for leaks
130 will be about your limit with an RA or R box although yours, being a UK car can extend the ratios if you keep your front & rear diffs. 3.9:1 as opposed to 4.44:1 for the RA/R iirc. You'd need to talk to someone like Paul at Zen Performance to sort the correct ratios. If you got hold of a DCCD box, the centre diff split would give a rear wheel bias anyway so, no need for aftermarket centre diffs.

Handle every stressful situation like a dog. If you can't eat it or hump it, piss on it and walk away!
Hi Richard,
How do you get on with the Compbrakes? I have the 278mm CompB4 kit on my STi4 (kept it small so I can run light 16" wheels) and have had mixed results. Lack of antirattle clips was a major pain until I got got thicker sleeves for the pad-retaining pins. Pad availability bit of an issue too, I use the 2 different types of Hawk pads - they have power enough for trackdays but not much initial bite.

Gerry,
The whole trasmission, diffs, and centre diffs combo thing is a nightmare isn't it? Added to the fact that I may need to think about a more robust 'box next year if I want to up the power into the big boys league and my brain starts to bleed. The centre diff idea was based upon cost in so much as I can get hold of one for about a grand and fit to my own 'box so I know everything works and don't need to worry about wiring up DCCD controllers and mating different ratios, props, rear diffs, drive shafts etc.
I hope it is not leaking as I have just had the inlet manifold off twice solving one. Does seem a little thirsty though even by scoob standards.
Andy,
I reckon the Compbrake setup very highly and am considering their rear brake set up fairly soon as I keep melting rear pads. The anti-rattle problem is a pain. I used to use some of the Delphi anti squeal stick on pads which help on the road as the pistons kinda bed into them and help a bit but as soon as you go on track they practically burn off and you are back to rattling along like a broken washing machine. If you are using the two sets of pad for road and track though it could work. I assume your calipers are based upon a Wilwood pattern like mine. If the kit came with a pair of aluminium tubes you can also convert from being a supalite to a dynalite user. I was hoping this might help with the rattle but it doesn't. The alternatives pads I have found so far are as follows.
Manufacturer With pins With tubes
EBC Yellow DP4007 DP4037
Ferodo FRP501
Mintex MTX-1795
Willwood 7320 7420
Hawk HP Plus HB101N.800
Comp Brake HP Plus Pro-race 1
I am currently running EBC Yellows at the front and don't like them as much as the Hawk HP Plus. Even less bite when cold but good on track and pretty durable.

Hiya, I believe it was you that pointed me here with my seat mounting question from Pistonheads?

I think mine are based on a Wilwood, yes, but they have one not two pins holding the pad in place. Could hardly believe the racket they made as standard. I've now got a sleeve several mm thicker than the one supplied to fit snugly in the pad groove which more or less quietens them down and seems to handle heat expansion just fine. Tried stick-on stuff and it never lasted long!Rustybin wrote: I reckon the Compbrake setup very highly and am considering their rear brake set up fairly soon as I keep melting rear pads.

I melted rear pads when I had 1-pots, so have gone for newage 2-pots.
