1. DDM is a FIRST CLASS company. My backbone was shipped promptly and I was impressed. The ProBeam arrived here in Central PA today eventhough I only ordered it Sunday night! GREAT service.
2. Packing and parts were perfect.
3. I used my Rhino ramps and front wheel blocks for the install of the probeam and all went well ( I used the same combo previously for the backbone install). It helps to read-reread and re-re-read the instructions first. Buy a good 11/32 drill bit - I bought a titanium tipped one, worth the $$.
4. After drilling the centerbeam and holding the probeam up to it I had a problem getting my one hand on top of the center beam to install the nut on the first bolt holding the probeam to the crossmember - my hand was slightly too large to fit up there. My son-in-law had a slightly smaller hand and got the nut installed. BTW, all of the previous poster are correct about wearing safety googles and a hat when drilling and installing the bolts. If you don't you'll be sorry. The right and left holes drilled through the center beam were accomplished with the probeam in place instead of removing it. I followed the directions to score or mark the drill holes, then took the attachment brackets off the wheels before drilling the holes to assure a vertical hole being drilled --- this was much easier. Once the 2 remaining holes (left and right through probeam and cross member) were drilled, I installed both right and left long bolts with the flat washers and snuggly attached the probeam to the crossmember. Then I re-attached the wheel brackes and tightened them to the wheels first before tightening to the pro beam. The secret is to not tighten the bracket to the wheels until the bolts/washers/ nuts are loosely attached to the brackets that run from the wheels to the probeam. Then it is a slow but steady process of tightening all of the the bolts. Probeam first, brackets to wheels secon and brackets to probeam last.
5. After I double checked to make sure all bolts were properly tightened, I took it for a spin. The rear end "feels" tighter and much more solid. After the car was properly warmed up, I punched it in 2nd and 3rd gear and you could feel the rear end was much more true than before.
6. The machining of the probeam, the brackets, bolts, washers and nuts is top notch. Directions are easy to understand.
Well done DDM!
Money well spent.
