What is the biggest brake disk that will fit under the standard 16" exige front wheel using the standard 2pot caliper? Obviously spaced out to suit.
Stock calliper is only good to 304mm although seen it pushed to 308mm
I don’t think I would use the word ‘pushed’ mate!.. 
All you need is some spacers… The OEM 2 pots still works great and the difference in modulation and torque is significant and for ‘normal’ non hyper modded BHP cars, I have yet to establish a reason why 4 pots are needed!
Personally, I have never run out of brakes in any of my 2 pot cars… but then again I am slow.
4 pots look cool however! 
Thanks. I found some 308mm Alcon disks on seriously lotus and some bells with the right pcd but can’t find a “kit” for that size.
I ran 315mm AP rotors on my S2 with no problems, under 16" front wheels
The 315’s were cheaper than the 308’s as well
Now we’re talking:) any ideas if there’s the same amount of space in the s1 and s2 wheels?
S1 wheels are an inch smaller than S2
I hear ya, and IMO the front bias is the limiting factor. 4 pots have slightly more frontward bias too.
My plan is to wang some more 2 pots out back, but with 38mm pistons (OE fronts being 44mm) and run 304mm all round.

I’m using 315’s on the front and they fit fine under both standard S1 Exige rims and TMR’s.
Also they are the much thinner rotor version so weigh quite a bit less than the 308’s.
Where did you get them? Is that with the 2 pot caliper?
Can I use a fully floating disk with standard caliper?
Rotors are from AP and bells I had made to suit. I’m using AP 4 pots.
Think you need to drive mine, you really need the 2 pots on the back with the bigger discs, for the first time ever the car actually feels correctly brake balanced.
yeah maybe xmas pressie tome
