Proportioning valve needed for LS1 conversion? Options

[mittelmotor]

Renegade Hybrids suggests doing away with the rear proportioning valve for their LS1 V-8 conversion, and replacing it with a T fitting. I know in stock configuration this could increase the likelihood of rear lockup. My car has the stock MC, stock 914-4 rear brakes and 911 "M" calipers & vented rotors up front. It'll also have a bit of tire stagger, 205s in front and 225s in rear. Will a T fitting be OK with this setup? Thanks!

Thanks for your input, Terry, but I have to disagree with your assessment of Renegade. Steve and Scott have been extremely helpful, returning phone calls and emails quickly, and providing additional photos when asked.

The quality of the parts I've received is absolutely top-notch...flawless welds on the radiator, a wonderful billet-machined bracket for the alternator, etc., etc. They may not make their stuff in-house, but they apparently pick excellent suppliers. Their cooling system comes highly recommended by many, and seems to be well thought out.

I think with my brake/tire setup, I'll be fine without the valve. That said, I'm not throwing it away either. I plan on doing some heavy straight-line and trail-brake tests to see how the car behaves in a lock-up or near lock-up situation.

OK Doug,

I can only try to share my experience with Renegade. I hope your engine mount crossbar doesn't still bow in the middle from being under-designed as they did in the past.

Renegade aside, my info on braking was real. So I invite you to try some SERIOUS late braking and trail-braking into a 2nd or 3rd gear corner on a REAL race track (where you are pushing to front-wheel lock-up) and see what happens. Of course, wimp-braking will get you by, but you will also be passed by a number of real drivers.

It's all you choice.

Best of luck,
Terry
