in fact no your calipers are bigger than mine in piston area.
mine are 6" sq. That's for the whole caliper ie. 4 pistons.
Yours are 8.08" sq. over 6 pistons, Wilwood quote the piston area only on one side of the caliper for some reason.
Therefore yours are 25% larger than mine. :rolleyes:
I think i see my way forward with bigger brakes, it's just how to keep the cost down is the issue as always.
I want to get them sorted before my run to Le Mans in July.
Ideally I'd like to keep my discs and bells and just increase the piston area.
I've been looking at the Superlite 4120-7568/69.
I'm not sure if I can make them work with the rest of my set up?
If you do not want to change discs (yours are 0.81" ?)you should look at the Caliper No.: 120-11137. The one you mention is for minimum 1.19" thick discs.
Also make sure you get adequate cooling to the brakes and use a high temp brake fluid (I use Castrol SRF). Pads are important too. I do not know how the EBC pads work, but the Wilwood polimatrix E really grab. I tried also Compound BP-20 , which is not so aggressive but tolerates more temperature.

In the end thicker discs dissipate more heat and your brakes last longer in a race. Maybe you can go that route and get same diameter discs.

BTW, what are you doing in LeMans.? What is going on there? I might be interested in getting there too. Let me know about it.
Best
Stefan

Front springs now 250lbs
 
Ended up getting new 250 lb springs. The old springs that came out were one shorter (about 1/2 inch) than the other. Probably from a hard landing in a ditch. New springs on old Spax Gas shocks are much better now, ride more comfortable without bumps trying to steer the car.
Will change the rear springs now. Will get one set of 250lb springs and replace ona pair and see. If it is not enough I can replace the other pair.
