Got rear disks?

the explorer rotors are solid where the cobra are vented. the cobra rotors will handle aggressive driving much better than explorer ones will.
good score on those.
just to get the info out, currie http://www.currieenterprises.com/cestore/categoriesre.aspx?id=1008 has disk brake kits like this for sale also for similar pricing.

 

I got mine from The Right Stuff Detailing, their website www.getdiscbrakes.com kit p/n: ZDCRD05 complete $395 which includes shipping. They have various rear conversion kits for our cars, with or with out staggered shocks, comes with e-brake cables, 11" rotors, calipers, all the mounting hardware etc.....this was by far the best deal around. You can also customize your kit, slotted rotors, with out e-brake cables, large or small bearings, powder coated calipers etc........
Using these with my 15" Magnum 500 rims, had to smooth out the welds on inner side of rims for additional clearance though........
