Beside the Miata are there any other cars in ST that would benefit from an Adjustable brake proportioning valve?

I already sent a letter to the SEB about it, since it would be a cleaner and cheaper solution than having to play with pads and/or aftermarket calipers.

I think it is a great idea

Rules creep. Bad idea.

So instead of spending a hundred bucks to get the F/R balance good, you instead have to mess with pads etc to get it right or go BBK?

I guess you'd be a fan of allowing fender cutting in ST* then. Instead of spending money on spacers and custom wheels to fit the maximum wheel / tire size allowed, you could just sawzall your fenders. Alternate radiators in ST must be a good idea as well. Instead of having to find (or custom make) a sway bar that works without interfering with the radiator, just allow alternate radiators. Huge cost savings.

Playing with different brake pad compounds to get better F/R bias is not a huge deal.

Use stock front pads with Hawk HPS pads in the rear. Or Hawk HPS front pads with HP+ rear. It worked very well on my 1990 STS Miata.

I tried larger rear rotor with bad results. Put stock front and HP+ and done.

Brake Bias is one step closer to SP. I'm waiting patiently to say no to this.

Agreed. Stock front, HP+ rear, straight from the Hollis blog. Works fine, easy, done.
