E36 325 drop links

[sniff petrol]

My recently purchased J reg 325i 4dr has just failed it's MOT for a couple of front anti roll bar drop links. Having a look at www.gsfcarparts.com there appears to be many different options:

B48150 ANTI ROLL BAR LINK ARM-BQ E36>10/91 12.90
B48150A ANTI ROLL BAR LINK ARM E36>10/91 9.00
B48151 ANTI ROLL BAR LINK-FRONT E36 M3 3.0 Coupe S50 92>95 16.25
B48151 ANTI ROLL BAR LINK-FRONT E36 M3 3.2 S50 95>00 16.25
B48151 ANTI ROLL BAR LINK-FRONT E36 M3 3.0 Cabrio S50 94>00 16.25
B48155 ANTI ROLL BAR LINK ARM-BQ E36 10/91>. 16.50
B48155A ANTI ROLL BAR LINK ARM E36 10/91>. 10.50

I'm looking at turning it into a trackcar so would it be worthwhile to fit M3 ones? (would they fit?) The car currently has the optional M-tec suspension but I will be upgrading to some decent coilovers at some point.

Any ideas?
