Most Tigers are limited by the mechanical grip of the front tires well before needing any additional brake torque. The rear tires make little contribution, unless running a torque arm...which (unless decoupled) adds anti-lift to the rear (which can also cause typical wheel hop stuff). I've never really understood running rear disc brakes on a stock suspension street car, but I may be missing something. Going to vented front rotors, however, seems like a reasonable mod to me, for a number of reasons..<br><br>Of course, if the car is used on road course or conditions where heat dissipation is really important, then discs all around make complete sense. <br><br>YMMV and all that <br><br><br>-----Original Message-----<br>From: Ramon Spontelli via Tigers <tigers@autox.team.net><br>To: 'Jay Laifman' <jay.laifman@gmail.com><br>Cc: 'Tiger's Den' <tigers@autox.team.net><br>Sent: Thu, May 11, 2017 7:22 pm<br>Subject: Re: [Tigers] Will wood brakes<br><br></div>
