50% was 2 of the 3 in tier 8. So you need 41.0 for 7.1, but unless you really expect another 60% sale on that car (60% saves you 30gp over a 50% sale), or you already have that car, it's worth the 15 GP to upgrade the brakes (and you get 10gp back for 50% anyway, so it only costs you 5GP in the end).
