Just a little point mk2 rs 2000 tre's are straight sierra ones are offset and handed, wont using straight ones mess up the track rod angle they will be pointing backwards slightly if veiwed from above unless you move the rack back aprox 10mm or the exact amount of offset in the sierra tre's whatever that is.
unless you mean mk5 rs 2000 ones which may or may not be straight I dont know
By the way i think you can use escort cossie ones they are offset
