First off all its called wheel fitment. Second of all if anyone runs stretched tyres, oni camber etc and expects to do really well at grip racing or racing in general is kidding themselves. Good wheel fitment and everything that comes with it is what makes or breaks a street car imo and in most cases bad fitment is why modified street cars are so god dam lame.

Also b110/b210 struts are a mear 5.8mm smaller in diameter than b310 and if im not mistaken stanza etc, whish is not a lot but i agree more strength. There ARE short inserts for the smaller 45mm dia, actually quite a few ive found, nothing like the range for the larger struts but not difficult to get something that works well. So unless you're after a specific valving then thats covered. So we are using oem struts, that are small, light and do the job. I always thought that 1200's arent about having lots of power but being small, light weight and agile.

I realise the full s13 setup on a 1200 might in some cases be the cheaper/easier option than modifying the standard struts, but i have found that it really isnt that expensive to get what you want. I really didnt spend a fortune on adjustable camber, ride height, range of spring rates, and the larger s13 brakes. In fact it was all done on the cheap. Obviously its not the only way of doing it and by all means go ahead and fit whatever you want but im always going to think that most of the time you are better off sticking with oem struts
