Sorry Ste for the thread hijack but it's relevant as yours is a precat too..
Hi Gary, the precats use a much smaller rear non vented rear brake disc & possibly different caliper than the later Griffs/Chims. I believe that's where the issue lies, therefore a brake bias valve is a potential solution. Have bled the brakes 5 times & done about 200 miles so I would hope that the new set up would have had enough miles to bed in, sounds reasonable? Using Ferodo DS2500 front pads & std rear pads.

I think I might drop mine lower and inset the wing top to make look a better job :-)
Ste .Yes, the vents can hit the reservoir cap. I changed the cap to a shallow Peugeot one, dropped the pedal box 4 mm and relieved the underside of the bonnet. Also made a cover for the reservoir as you can see the reservoir through the vents

Which brakes did you go for Ste? I've just fitted a high specification kit & the brake balance is verging on dangerous with the rears locking way before the fronts get anywhere near. I've emailed & called them today but no reply or answer yet.
I am currently in the process of fitting an uprated brake kit to my 430 Precat. I went for new 4 pot front callipers and 285mm discs to fit my 15" Gotti's. Because of the potential to over brake at the back, I am leaving the rear callipers as standard and just giving them a repaint. To compliment the setup I am going to fit a set of new grooved standard solid rear discs. The earlier Griffs were 'under-braked' at the front, so I expect the new setup to give better braking performance without causing the rear to lock up. To answer another question posed, there is a brake pressure balancer at the back (well there is on my Griff). I believe it is a Land Rover part as it is identical to what is on my LR Defender.By the way I went for the front kit supplied by Hans.
Regards, Pete

Thread jacking lol I don't mind !
Hans that's the guys name should be over next week ? Think his 4 pots are good value for the money ?
That's some lump steve !! Nice think I will stick to the turbo route ;-) I will be looking for a T5 gearbox !!
Anyone ?
Ste .
You want a T5 from a Tuscan. Apparently they go straight in without any chassis mods. I also think jonn reid can supply you with the correct fitting for the T5 if you can't find a Tuscan one.Hans that's the guys name should be over next week ? Think his 4 pots are good value for the money ?

And that little lot probably took you less time than it does for me to change a wiper blade... threads like this amaze and depress me at the same time

Cheers ,I found a Tuscan box but a £1200 thought it was a little steep ?I think stevesprint went this route. Give him a shout.
I will be looking for a T5 soon and will be in touch Mr Reid for some parts I recon I can get a T5 for a few hundred with contacts in the trade as a 1 off favour :-)

Had a look at the brake bias valve - on mine its inboard of the OSR, it looks like an inertial device. I'm not keen on this type of thing & am going bypass it & fit something like this-

Sorry a little off topic but you did ask.
Fitting the later style T5 with the lever further forward is one of the best mods I did to my Precat Griff. The Griffith 500 external gear lever linkage would foul on the top cross member, Quinny can confirm.
I personally welded the Griff 500 style gearbox mounts onto the bottom chassis rails but you don’t have to as g8ape designed and fabricated his own cross member utilising the existing cross member bolt pick up points on the chassis. It might be worth contacting g8ape as I know he had a few extra brackets made. He also had some beautifully machined gear lever adapters made.
You can contact him from this thread. http://www.pistonheads.com/gassing/topic.asp?h=1&a...
You can see some of my T5 pictures here
http://www.pistonheads.com/gassing/topic.asp?h=0&a...
You’ll also have to change your Speedo to one of these from speedy cables.
They are definitely worth the 3 months order time as its a perfect match and the calibration is programmable via the trip-reset button plus they work with virtually any road speed sensor. Don’t forget you'll also have to fit a new speed sensor on the top of the diff. As your going the Turbo route I assume that means you won’t have to worry about compatibility issues with the old 14CUX ECU that I'm obsessed with.
If you are serious about this mod I’ll email you some more pictures.
Good Luck

After my last post above I thought best I get this thread back on topic.

Seriously yes I will need a better box if I am looking to get 400 ponies !!
I take it the one on the right is the std box and the one on the left is the Tuscan ? The one to fit ?so you have to mod the prop? Speedo do they need my old one as I will order that now ?
Fabrications ? I am a fabricator by trade so have access to CNC plasma and lathe ,milling machine tig for alloy so drawings would be good or a pattern and I would make a better one in return ? (A long time ago I was going to fabricate a Griff chassis in stainless steel )
Yes any help in this conversion will be appreciated ,swaps beer tokens in return

i had one on my ls griff. definitely vented a huge volume of really heated air, especially at standstill. make sure you get the brake master cylinder looked at or it'll possibly interfere. it'll just need some fettling to work.
When you say fetteling and also have been told lowering the pedal box can you clearly explained ,as my peddalbox is touching the steering column ? Do you mean undo the bolts tilt it forward and slot some spacer washers between the box and body so it tilts it forward by 4mm?Ste.

yes, space it off the body by a few mm to drop the fluid reservoir a little. i didnt have any issues with the steering column though...but these cars are all a bit handmade!Ste.

Ste.
I inserted 4 spacer washers between the top 4 mount bolts that are accessible from the engine bay, this lowered the whole pedal box and also caused my lower left mount to hit the steering column. It was only a few mm and was soon sorted with a hand file and yes I also elongated the 2 bottom bolt hole in the pedal box.Ste.
I did this 4 years ago and has been absolutely fine.
Anyway back on the bonnet subject 
I had a lovely levern bonnet stay a few things broken but may I say quickly replaced (thank you) so the thing was no rollers ? you would think these things never wear out ? oh yes they do and who made the decision to have made them white ? YOU CANT GET THEM BLACK !! 
So this is what I did today and got some lovely domed stainless allen bolts to finish them off
