Group buy: 2pc wortec rotors for steel super brakes on f-type

That part - cumulative effect of removing 100 lbs of unsprung weight with forged wheels and calipers (25 lbs per corner) has to be of noticeable benefit. My goal is to get my 3850 lbs "sports car" to 3650 lbs, so it can compete with my 4 door sports car M3 around corners. Can't hurt acceleration either, right?

I'm shooting to get my car as close to 3500# as possible: CF wheels (80#), Wortec discs (50#), Lithium battery (30#). It'll take a few social security checks, but I'll eventually get there.

I only mentioned the rotational inertia as a minority benefit. It's definitely significant on motorcycles, though, where I have considerable experience. There, it also affects steering. I noticed a slight improvement in acceleration with tire/wheel swap on a grievously underpowered car, but doubt I'd feel anything in that respect with the F-Type.

IronMike, Any decision yet on which edge?
Gibbo, Are you still certain you want the drilled only?
lizzardo, Do you still prefer the slot only option? I'll check to see if Paul will allow us a 4th option.
I'm going to contact Paul Monday afternoon and want to give him the details as closely as possible so he can move quickly once he gets the OEMs in for measurement. Obviously, he will not begin fabrication until the payments are submitted.

Unless you have eight corners on your car, that's only 100# savings
. Where are you getting the other 100# ?

VAP exhaust + downpipes (15#) the SVR exhaust (35#). The VAP lowering springs (12#). 2018+ seats (17#). Converting non aluminum body parts to carbon fiber and going to the gym are other options.
Non-weight saving mods
spacers, bigger/heavier tires, a wife/gf

Why/how does suncut improve cooling?
Does the outside edge of the pad leave the disk, or is the suncut edge outside the radius of the pad?

I'll put long odds that the "suncuts" mean the edge *does* leave the pad surface. I can't see it making sense any other way. Otherwise, it's just extra metal to cause clearance problems for the caliper. As for how it might help cooling, I can think of some possible mechanisms. e.g. helping pull more air through the vents. We'll see what Paul has to say.

I've got an SVR with carbon pack and carbon roof. Its also got the 20" forged wheels which are around 12kg each.
These 2PC brakes should save me another 20kg so at a guess will be around 1690kg.
Just wondering if there is anything else I can or did the SVO team pretty much do what could be done without making this GT into a more out and out track car?

I forgot about those 2 items as well. I might just make it to 3500 lbs.

Paul would have to go back and order a set of 326 rotors to take measurements. Unless he gets an order for five I don’t know how likely he is to do that. I will ask.
