hispec ultralite 4 on 318is e30

[IlovM42]

hello people.
just a little question about front brakes upgrade.
I have found a set of cheap Hispec Ultralite 4 calipers, same as this http://www.hispecbrake.co.uk/UL4300.html and I was wondering if they will be ok for my lightened E30.

Assuming this calipers are use on car lighter than mine but more powerfull and also with wider/stickier tires I think there will be no problem to use them in my E30 as I will surely use 205/55r15 michelin PE2 for the moment and maybe some federal 595 RSR later.
My car is going to go on track sometimes but a usually use it as a daily.

what do you think? is they're someone who know those calipers? is there any risk?

thanks in advance
