From mini spikes to mini pins
 

Have been using mini spikes on my B44 since my return to 1/10th indoor (2 months) on carpet/polished surfaced but going through a set of Schumacher yellow compound mini spikes every 2 club days,so an expensive time!
Tried mini pins because aparantly longer longevity but i really cant get on with them,car feels way too edgy..am i missing something? maybe trim the outer pins?..or do i need to change my driving style

Pins drive very differently to spikes, you get more steering in general and they are a lot less progressive when they lose grip. They either have more or less grip than spikes, nothing in the middle.

You have to be much smoother with pins, although most of the time they are still the faster choice. In my experience for club meetings indoors spikes have about 3x the useful life pins do!

I run pins indoors on polished floor. we seem to have a even spread of racers using full spikes, mini spikes and mini pins. I can drive on either of the choices, but prefer pins personally. suit my driving style more. :)

For 4WD front mini pins, I grind off the outter 2 rows of spikes. (for running on carpet tracks)

Cutting rows and changing the setup / geometrywill make pins easier to manage.

I ALWAYs remove the outer rows on mini pins as the only time they are giving you anything it's when you don't want it IMHO.

one row front & rear tyres? inside & outside?

Always 1 row off the outside, before the glue is even dry :p

For me the problem is the tire has such a square profile so the outer edge only really digs in on roll rather than the car rolling on to it if that makes sense. The result is a sharp change in available grip ... especially when you are landing from jumps slightly off square etc. Cutting the rows makes the car "safer" without loosing you any straight line traction ability (as that row isn't really loaded when there is no roll anyway)
