Hi All,
I know it’s been asked on here before but I found conflicting information.
What’s the biggest sized disc you can practically use on the S1 Exige while retaining the stock callipers. I know on the rear you’re a lot more restricted as you can’t space the calliper out, but what about the front?
I seem to recall the AP290 discs JUST fit the rear, and you can go up to something like 304mm on the front?
Can anyone confirm?
Hi Mate!
I have Alcon 308mm on the front! With standard callipers.
They need about a 12mm spacer.
There is a noticeable difference in modulation with the better torque having the calliper further out. MUCH nicer on the pedal. Of course, the innermost 12mm of the disk face is left unswept.
Have a look at these on the seriouslylotus web site.
Hope all well in NZ!
Cheers,
Pete.
P.S Did you have your car re-sprayed??? Looks great!

You can get a 315mm disc that fits the normal 295/304/308 bell.
I have 308/295 Msport combo on the Audi with JSR bias Pedal box and PF01 pads and its just mint …
With stock calipers all round, I don’t think I’d want to go bigger than 304 up front… and I don’t think you’d get anything bigger than 290 on the rear.
Even with 290 on the rear, I had to dremmel a very small amount of the calliper to stop it touching.
With 304 on the front, the pad doesn’t sweep the whole face of the disc…the bigger you go with the disc, the worse this will get.
304/290 with Performance Friction front pads and Pagid rear pads with standard master cylinder was a great combination for me.
The 308’s fit fine on the front.
I had perviously had AP 304’s on the front, they were great too (aside from surface cracking) but there is a noticeable difference with the Alcon 308’s. Of course there will be an un-swept area on the inside of the disk… unless you increase the pad surface area this will always be the case. But, there is not problem with clearance between the calliper and the disk.
The major benefit comes from the greater diameter of the disk increasing the torque the pad can exert further out from the wheel centre. This means for a given constant pad pressure against the disk, the braking force is higher. But for me, the bets bit is the better modulation and feel that is available as a result.
I will be needing them before long… the EBCs are really at their limit on some tracks now, don’t expect them to last much longer!
