  1. They came with the car when I bought it. it seems the consensus is that while not a lot faster than the cup 2 tires, they are more consistent and take more punishment for the wear. No rubbing. Just cleaned my wheel wells and no sign of them touching any part of the body on the stock rims. Jpr
  2. Here are some pictures of my car fitted with the RE-71R Bridgestone in 225/45/17 front and 275/35/18 rear. Jpr
  3. Im running 225/45 front and 275/35 rear using Bridgestone RE-71R and they work well with no rubbing that I have been able to feel or see. It is important to check the actual tread-width on the selected tire as they do vary for the same size.
  4. Hello, Has anyone modified the front hub bolt patter to match the rear?. It would give us a wide choice of aftermarket and high quality wheels. I would appear that its only weld/fill the existing wheel bolt holes in the hubs and re-drill and tap for the new 5 x 114.3 bolt pattern. the hub diameter can be adjusted with a centering ring on the wheel.

  5. I agree with you Jack, that 12.5 a/f as a number is not necessarily bad but in the context of a midrange rpm a/f, it is definitely rich. Most of the tuners tend to favor a/f in the 13's in this range and save 12's for the higher rpm of max power. As you pointed out, this is all case dependent as we dont all enjoy the same fuel quality so an overall setting for the whole world will tend to have fail safe numbers to protect against premature failures. However, with our v6 setup (smalllish SC that is already past the peak efficiency of its operational range), fuel is used to counteract higher IAT. My aim would be to manage IAT with another tool other than fuel. Jpr
  6. Agreed. But there is nothing wrong with optimization. I'm afraid that the rich condition compromises the lubrication by washing the cylinder walls, and robs performance. If the aim is to keep IAT down, then an intercooler or methanol is a better choice than fuel.
  7. 12.5 is still very rich. As if the ECU tuning is using fuel to cool the mixture to avoid knock. the conventional wisdom is to lean out for torque and richen up for power on the top end. Methanol injection would be a better tool for that and take less space than a charge cooler. Jpr
  8. I think that it is more to do with the door hinge than the striker pin. If I lower it then the door might out of square. Maybe the door hinge bearing is worn and needs to be refreshed. Jpr
  9. The passenger door on my Exige is well adjusted and closes with ease. The driver's door is lower and hits the striker pin and has to be had driven to close. How can I adjust it so that it is aligned like the passenger? Thanks in advance, Jpr
