I bought the Baer track system for my Mustang and it set me back almost $1000.....for the fronts ONLY and it's just 2 piston.....stops better and much less fade, but not as good as I expected for the money. But when I looked at all the other sets running over $2500, this was the only way I could reasonably go. Damned cars. Eat up more cash than my stupid audio systems.
That's why I have pretty much quit building cars altogether. Sold the Mustang, bought a Honda Ridgeline and pretty much only do my cafe bikes now. When I added the receipts for that particular car after selling, I wanted to shoot myself.
(but a Paxton charged 4.6 on an Eaton 4.10 LSD is definitely fun. Can hang with a new 1000cc sport bike....but, unfortunately costs 5-6x more)
