HPM Mega Byte Jr Question

[98midnight]

I'm wondering what the hole on the top of the brackets on the mega byte jr's is used for. it looks like a bolt is supposed to go through there but not sure. Any input would be appreciated.
Thanks

They offer two different mounting points, they claim 85% more traction with the upper, 135% with the lower Typically on a street car I have them in the upper hole, the lower hole is very aggressive and it more set for a track only type of set-up....it all depends on the rest of your set-up.

Make sure you double check your pinion angle...shoot for -2 to -3 degrees down

Hope that helps
