I think for the first time ever I started to reach the limit of the two pot brakes yesterday.
I had a couple of moments when I left it late and the things just felt like they would not stop me.
I have probably been pushing my luck a little with the power hike and the weight of my car but in honesty I have always found the brakes to be fine. It may be the CL5+ pads but I felt the pedal start to go once so I came back in before I boiled the fluid (which is new).
Sadly due to the new house I’ll not be doing many TD’s this year so no point doing anything yet but I think I’ll invest in the lotus 4pots for next year, I’ll probably go with the standard rotor ones as I am not convinced I really need anything more.
I am thinking the same Andy and looks like AP 4 pots will have to go on my shopping list.

I alway believe IMHO 
that any great increase in engine power should in corporate better brakes, be it a change of pads or calipers merely to give that edge of safety. 
So as soon as you have the pennies…
Change the pads booth, they are rubbish.
I love my 4’s…
Cheers guys. Gav thats the plan, I am not a fan of the CL5+ I really do not like the feel they give. Twas the fluid getting hot that bothered me tbh, I have boiled it once before and it was starting to happen again.
Now that could just be me not being very good on the brakes maybe I need more protection from myself 
Seriously though I figure the 4pots give more surface area to remove the heat and maybe I will not need to stamp as hard.
I think the standard lotus kit should be fine with the solid disks I would just rather have it with better pads than the ferodo’s maybe some 42’s.

Try CL6’s.
Been very happy with mine.

boiling fluid - change fluid, jobs a carrot, not sure 4 pots will solve that?
yeah when was the last fluid change? made a world of difference to mine, however the 4 pots on wills made me realise the value of the 4pots.
do it in stages, get the 308 rotors and bells when yours wear out and run spacers and the 2 pots, then when funds allow buy the 4 pots
Out of curiosity what tyres are you running? They are part of the braking equation but can be easily forgotten.
I’m sure the racers will comment better than me but when I ran some second hand slicks on a few trackdays the improvement in braking performance was incredible; so i was wondering what the relative performance of various tyres could be and whether they could be a differentiating factor?
Ali bells, big rotors and RS-14s
Fluid was changed twelve months ago after the last time it boiled, it was swapped for racing fluid and has only done two track days and very few road miles. It did not boil this time but I felt the pedal going soft so came in.
My theory is that although the two pots will stop me I am having to use more brake force and overheating the smaller pads? As I said I had a few moments when they felt they were giving up on me.
Tyres are R888’s, car is 920kgs and 260bhp, rotors are 288mm.
As I said earlier I do not think I need an expensive race setup but the standard solid rotor 4 pots with good pads will probably help.
Like I said when I saw your discs on our meetup m8 they look like they are on the wrong way round …Could you check that out 1st maybe before spending your Gearbox Fund ?
‘Fluid was changed twelve months ago’
I think thats where most of your problem is. Fluid should be changed every 12 months or so, even more often if you have used racing type fluid. It has nothing to do with usage, its all about life and how much moisture there is in it.
Ask yourself this, did bleeding the brakes last time sort the problem out the next time you used the car on track? If so, then I think you have your answer.
Haven’t got one but often wondered whether these would be accurate enough to give an indication as to when to change fluid:

Is that made by them Clearblue people ???
What fluid did you use Boothy?
Bigger disks with the standard calliper will be a better first step than 4 pots on the standard sized disks. Its more about leverage than pad size and piston pressure.
Put SRF in and then fit some PF pads and jobs a good un.
Sean and John, as daft as it sounds I am not sure. Last time it boiled I just sent it in to CN’s and asked for a fluid change to high performance fluid. I am pretty sure it was Lotus sport branded though if that helps?
I did have SRF in my last car but I just went to the dealer this time.
Sean the upgraded 4pot kit comes with 308mm rotors, they are just solid and not belled (probably the same that came on your car?).
My theory on getting the kit is that I would have to get 308mm belled disks and spacers which are almost the same money as the lotus kit, then the cost of every set of disks would be higher than the solid disks long term. I am totally ready to be corrected but from what I read people seem to suggest that there is more difference in brake force from the pad and disk size than anything else. So I figured that fitting the lotus kit with better pads would be better than Alcons and 2 pots.
That reflects my thought to !!!
