I had these for years on my old Eddy, great little 4 pot BBK and once twined with a slightly better rear set up they more than handled my 2+ power. For less than £1k fully refurbd with new everthing and inc fitting it's a win win. Yes there are better set ups on the market but not many for sub £1k. If you're not refurbishing them and using your original discs and fitting yourself.....less than £600 I bet.
Actually, the p/ns 986.351.421 & ..422 show as front calipers on Google?
Correct. The NQSBBK are front calipers from a Porsche.
First three are the model number 986=Boxster, 996=911, 955=Cayenne etc etc
351 = Front brakes
421 Left Caliper (odd numbers) & 422 Right Caliper (Even numbers)
Dont buy anything with a 352 in the part number they are rear calipers and the pistons are too small for a Mk5
