Stoptech V8r brakes are great! Need to change rear compound to something with less bite. Got some XR4's on the way.

With the 1" master and sport booster they are still a bit touchy for good heel toe blipping. Ideally I would convert to dual manual masters but that's not in the cards right now. As silly as it sounds I am gonna try adding a couple of big springs to give more pedal pressure. Pretty primal but I bet it will help.

I have no issue with standard '89' 1600 master cylinder and the 11.75" fronts with Goodwin (old) v3 rear (same size as sport I believe)..Carbotech/G-lok pads.

In fact I am scared to make any changes because they are that perfect..... but then I like a 15 and 16 mm rear sway bar too....must just be me.

Both my front and rear calipers have larger piston volumes than what you're running. It's not a great comparison.

I am serious about rigging up some springs to add pedal pressure. Kinda getto but should help with the problem till I can give it more attention.

Moving onto important things....Working on gear ratios for the new sequential. Plan to pull the trigger this week.

7.3.2.a.1, right? Greg confirmed? I have a set for Rover, pulled them for PTE years ago but was considering adding them back mostly for ballast.

Yup that's the one. I even asked Greg for an exception so I can repair my caved in ones. I also explained they were nothing more than floor supports. He was not having any of it. Said they would assess points for the "mod" if I altered them from the originals.

I can forward you the email exchange if you like.

Sorry late reply....somehow missed your post.

It's classed as SU just to make things easier as we shake out the car. I crunched the numbers and it will fit in ST2 pretty easy with some tweaks. That class is not that great in my region though. ST3-ST4 is where you want to be for good racing. ST3 looks very doable. ST4 will be tough with the non OEM roofline and pending sequential.

I need to optimize the saline interface over the next few events. That's really what's holding things back at the moment. The extra power and grip helps overcome some of that to make racing more exciting.
