Planning, planning, planning....
Trying to figure out if I want the 02M (6-speed) or the 02J (5-speed) with cable shift for the Scirocco.
I came across this really, really, really cool site that I can put in all the gear ratios, tire size, etc. and watch it go through the gears using the auto-shift button.

I haven't tried the numbers for the 02J or 02M on the site yet. That will take some time as I need to determine what I have first.
I figure that if my Golf can get into 6th gear at Okemo (just holding speed, not accelerating), the Scirocco being lighter and much smaller diameter wheels will be hitting 6th as a usable gear.
Of course, what is it like at all the other speeds and gears..... what about Burke (tight hill) vs. Ascutney (fast)?
The 02M is much stronger, but since the car is so light, I do not think I need to worry about breaking the 02J. So, strength is not a reason to go with the 6-speed.
Then, there is the weight difference. I think it is 100# (02J) vs. 112# (02M); assuming the internet is correct. Will have to weigh both of them when I get a chance. Of course, the 02J doesn't have an LSD, but it will give me the general idea.
Of course... bringing in the cost factor. I have the 02M freshly rebuilt and ready to use. I have the cables for both. Might go with aftermarket upright shifter.... we will see.
Both transmission will either require some fabrication to be able to use the normal MK4 (like my Golf) engine mounts OR order pre-made 02M or 02J to MK1 (Scirocco) mounts. Since this will be always raced, I want something that will hold up. I like the fabrication angle as MK4 parts are easy to come by.
