RE: JT Racing MT2
If JT isn't going to offer a stronger design I'm not that interested in them either. I would end up shelving them and using the stock towers.
A smaller hole will be fine and I think that the lightening cuts are unnecessary, they make the part look good at the expense of some strength and the weight savings isn't going to be that great. The shock mounting holes are fine, they offer plenty of adjustment options. I think that the overall outline of the JT tower is also fine I see no reason to change it.
The price should come down quit a bit if the hole is smaller the lightening cuts are not made and you do the cad design. The majority of the work could even be done on a water jet and then the cnc for the shock holes, thats if a water jet can't do the holes I'm not that familiar with them.
