Racing Beat is pretty good about no BS, so when they say something I tend to trust them.

I'm looking at upgrading the sways for less body roll, but I'm not crazy about drilling into the car to install them on the control arm.

I'm into some moderate auto-x (for fun, I don't compete) and maybe some track days for fun. How necessary are these upgraded endlinks? What kinda force does it take to snap the stock ones? How worried about this should I be?

 

Racing Beat said during the focus group meeting that unless you do a lot of auto-X the stock end links should be fine. If you wanted the extra insurance I would only replace the front end links with the RB ones. Based on the fact that the RB rear sway bar ( .75” diameter x .125” wall thickness) is smaller than the stock front one (1.05” diameter x .134” wall thickness), the stock end links should be fine in the rear.

 

I don't get this logic. Racing Beat only sells front end links. They don't sell ones for the rear.

This doesn't make sense also. In stock form, the rear end links are smaller than the front ones. So comparing the RB rear sway bar to the stock front one is apples and oranges.

Oops my bad, I was thinking that all 4 were the same, they have the same ends. I missed that the rears are shorter in length. I never had all 4 out at the same time.

 

for those installing the endlinks, how are you drilling into the bar and control arm? Just a power drill?

 

Racing Beat provides both the drill bit and a collet to help guide the drill. You don't really need the collet; it helps marginally with the alignment but you have to stop midway and clear it of chips before finishing. And yes, a hand drill.

and this is easy to do? I've never drilled into metal, I'm seeing like sparks flying and stuff, maybe I'm making mroe of it than i should

 

I used my 18 volt Craftsman drill and it was a breeze. However, I have a few years experience with mods and fabricating. I wouldn't suggest that anyone who may be hesitant or inexperienced with power tools take on this task because when drilling the aluminum control arm, one slip of the bit and you're gonna need to replace the whole arm.
