They come with thick drilled and threaded aluminum bar stock that fits into the front subframe. You thread the bolts into them through the two holes in each of the subframes. Thus they clamp on the subframe for a very strong grip.

get umi 3 point weld on subframe connectors. I am about to order me a set for my car. The weld in are so much stronger than the bolt ons. Just remember to disconnect your battery before welding on the car it can destroy electronics.

I have weld-ons on my A4 car and I didn't like the impact harshness they added to the ride. But I'm stuck with them. So far, I'm liking the bolt-ons on my M6, but if I decide someday I don't, they're off and sold.
I just dont know how those things are fitted/bolted on. Havent seen them or bolted on the hardware myself so its hard to imagine what kind of fit they would have but you dont have to think to hard to know a weld is gonna hold over a bolt. IDK about you but I have seen bolts losen up on wheels lol
The hardware used to bolt them up is grade 8 if I'm not mistaken and they are a perfect fit.

the main reason i went with bolt in is just the fact to have them welded, you need either a welder or pay someone to weld them in. i was able to do mine in my driveway, that was in 2004 with no problems. like everybody says you can always have them welded in, i cant see it being that much diff between the 2 styles if you change your mind later.
I ordered a set of the weld on subframe connectors from BMR. I will say that i was more than impressed with the quality, fit, and finish. NO REGRETS!!!! VERY HAPPY WITH IT!!
Also, I noticed that after installing the subframes my car felt a bit tighter as far as on the turns. My only mods are BMR lowering springs, adj. panhard, and subframes all BMR.

So I bolted them on the other day and it actually straightned out the subframe lol, but man the difference is huge the car pulls straight now cant believe they work that great, my car used to pull left bad now its straight as can be on the launch thanks guys

You guys can talk about the bolt-in subframe connector all you want but without a shadow of a doubt the weld-in style connector is a superior design as far as form and function go. If bolt-in connectors were so awesome you would see them on all the real fast cars.

i have the jegsters (they were thrown in when i bought my headers) but i havent installed them. when i went to install them, i found out that i had to drill out the 2 holes on the front subframe and that made me stop installing them. im thinking of getting them welded in one day..
