318ti STW vs. 323ti

[alexk]

Hi guys,

I am a new member. I live in Switzerland.
I drive an E90 325i and an E46 M3 CSL.
I want to get something smaller and eventually convert it to a racing machine (rollcage, buckets etc).

I am between a 323ti and a 318ti.

My first question starts here.
I found that in CH there are some 318ti marked as Limited Edition STW version (46 cars in the world).
You can see an example here -> link
What is obvious is the M3 package, the lightweight BBS wheels, alcantara interior and label in the dashboard.
Do you know any more details about this version ?

Also, do you think a 318ti would perform better in the racetrack (Ring especially) than a 323ti ?

Thanks
