whats the most common brake upgrade that people do?
keep looking at various brembo set ups on ebay, are there any pretty much bolt on upgrades?
or is the best bet to go for something like porsche ones and get brackets etc made up?
what sort of cost would that entail?
got 17" compomotives on at the moment so will obviously need something that will fit with these wheels...
many thanks in advance,
nick.

Not sure that this is common, however I'm just in the process of putting a Hi-Spec ( http://www.hispecbrake.co.uk/ ) upgrade onto my Griff. Simon at Leven is sorting the details out for me at the moment 
Sportmotive do a willwood kit in 4 or 5 stud applications from £699 plus vat

Just put a set of Wilwood 4 pots on mine from TVR power... Stunning performance, absolutely love them!
You mean fronts only? Just the calipers or have you upgraded discs and pads etc?-300mm vented discs (they look huge compared to the standard 500 brakes)
-4 pot calipers - very light I might add compared to standard
-braided hoses
-racing pads with a HUGE amount of meat on them (Wilwood racing branded). These pads are extremely good with good cold performance and amazing hot, the only downside is that they create rather a lot of brake dust! They are so thick that I would think they would last quite a while though!
Now that they are fully bedded in, I am going to get Tuscan racer pads put on the rear (as the calipers and discs are the same), with braided hoses at the back too as per Power's recommendation. I'm not sure it needs any more for the road as the current setup is like having a large anchor deployed when you hit the brakes, but I plan to track the car so I might as well!
One big improvement over the standard brakes is the level of control you have, there is much more progression in the brakes so they only bite hard when you want them to; around town they're still very well behaved - great mod!

Bugger! Why can't your shop be nearer to me Joo??? I did save a fair bit getting brakes and shocks done together but still... That is a fair markup. The only saving grace is that they were put on and set up by an extremely knowledgeable guy who set up the TVR GT Cerb and Speed 12 as well as loads of other rather tasty cars (had good chat and a flick through his photo album!). No regrets though, the car handles like a go-kart now - I'm astonished at how much further the limits are now. Its like its on rails, I keep going into corners faster and faster expecting to end up in a pile of broken plastic and it just goes around without any drama - fantastic!

Like the control thing. Can you describe pedal feel in relation to progression? I like a hard pedal with firm feel. If you've ever driven a Citroen or Maserati with hydrolastic brakes, I loved the way they feel. Not saying I need the same abrupt sharpness in a 'normal' brake, but I like driving with minimal brake effort applied from smooth unclumsy action to a hard pedal.I would like to change the rear calipers when I change the fronts.
My reasons are aesthetics of them matching the front calipers, plus improving the handbrake if possible.
Have the people who have fitted the AP racing calipers from a later TVR, fitted them to both front and rear? If so, does this give good balance?

The problem is the that the later cars AP rear calipers have a seperate handbrake caliper and the thought is that the change to the rear assembly would be too much aggravation to achieve.
Hans was doing an upgrade for the rears as well, but the performance I get from mine is easily enough to justify leaving them as the standard calipers.
Aesthetics is a diffeent viewpoint though. I have Hans kit on the fronts and I would only recommend a brake upgrade once you have sorted the dampers out as the weight transfer they can create is far greater and swifter than the originals, in addition the bias is more towards the front. Without the dampers being sorted it may produce interesting heavy braking moments.
On this years hoon, with Ferodo 2500's all round and 5.1 fluid I still managed to boil the brake fluid on our Turini, Vence, Verdon and Ventoux day

it inspires much more confidence when coming into a fast corner or roundabout. There is no fear of locking the wheels or squirming under braking any more
I thought I was driving pretty hard, and I've not really got any complaints of wheel locking or squirming. Have rebuilt calipers with new discs and Ferodo pads. Drilled discs up front of course. I assume my fast driving style is not that different from other Griff fast drivers. That is, driving up as well as down the transmission using engine braking just like when riding a bike fast. Maybe my brakes are good, which I believe they are, so it's still that hard pedal feel I'm thinking where the pedal is more like a switch that requires delicate input that offers sharp but controllable response.Interesting, and thanks. Some good info coming through.
