Rear wilwood dynalite or superlite

[keith4909]

I have both and can sell one of them. My main question is whether the expensive kit is worth the extra cost. Not really road racing now but you never know what the future will hold. I have both because I bought the superlite before I found a 12 bolt diff. I then find a 65 chevelle 12 bolt that is complete with a wilwood dynalite setup



Dynalite with 12.18 rotor
4 piston caliper
3.00 surface area
.80 thick

Or


Superlite with 12.88
4 piston caliper
1.98 surface area
1.1 inch thick




Car has front 12.88 six piston
Will be swapping 7/8 master for a 15/16 master
1967 Gto
Turbo 400
474ci roller motor
18" wheels
275/30r18
245/40r18

I would run the smaller set-up/rotor dia. in the rear. The very worst thing you want is too much rear brake when going around a corner. Brake push is always better than brake loose. You don't want the rear coming around when you mash the brakes...

Just my .02....grr

Hey Sean,
That 12.88" x 1.1" rotor weighs 12.3# which is almost 3# heavier than the 12.19" x .81" rotor. In my experience, rotors around 12#+ typically have sufficient mass to handle the heat we typically see with Pro Touring cars on road courses ... if that matters to you.

The 3.00" piston area from the smaller kit will produce 50% more clamping force than the 1.96" piston area from the larger kit. Even though the rotor is smaller & the dynalite caliper is not as rigid, you will have more braking force from the Dynalite/3.00" PA/12.19" rotor combo ... than the Superlite/1.96" PA/12.88" rotor combo ... until they start to fade from heat.

But one of your highest priorities should be creating a balanced braking bias front to rear. You need ABOUT 70% front braking force & 30% rear. So if your Wilwood 12.88" front brakes are the 4.04" piston area Superlite 6Ps that I think they are, the kit with 1.96" piston area & 12.88" rotors will be very close in balance. Figure out your front piston area & let us know.

:cheers:

Thank you very much Ron. That's the exact info I was looking for. I assume the brake bias will only need an adjustable prop valve. I have a valve already plumbed in because I was originally going to retain my stock drum. Obviously the superlite is a nicer looking kit but if it's more expensive and offers lower performance for my needs than its a no brainier. Thank you again
