I ordered a set of Sparco 4-Points last week. I was thinking of drilling a few holes into the stock rear strut bar to bolt the back Sparco straps into it. Should be safe be enough.

The stock rear strut bar isn't very big to be drilling into it. If anything you should try and weld up a piece of angle iron and then attached the harness to the angle iron. This wood make it a little beefier.
although the 14's are small, the are extremely solid and huge threaded. normally i wouldnt do it, but i think they are pretty safe. they are not much bigger than your stock seatbelt bolts.

Thanks guys. Looks like I'll have to either buy an aftermarket bar or better yet,.... bolt the back straps to the floor behind the seats.
Didn't really like the idea that the back straps could be seen through the rear window bolted to the R/S/B.

THE STOCK REAR STRUT BAR IS NOT FOR MOUNTING HARNESSES TO
A harness must be mounted to something solid. A 3 point harness may be mounted to the chassis at the left shock tower itself (NOT AROUND THE STRUT BAR), but a 4 point needs some sort of harness bar (such as the M2) or cage to fasten the shoulder belts to.
The stock rear strut bar has very flimsy attachement to the chassis and the bar itself is only a small tube of steel. Most of the "bulk" you see is plastic padding. There is no way in hell that a shoulder harness wrapped around the stock bar is going to save you; the entire stock bar assembly will simply bend and let you slide forward.
If you want belts so you can be "cool" do whatever you want. If you want belts to save your butt whenever everything goes wrong, you do it the right way.

I know everyone can find hundreds of pics of belts installed other ways. That does not make it right or safe. This is common knowledge from the harness manufacturers themselves.
The m2 bar fit just fine for me.
guys damion is right, The stock bar is a flimsey POS. Look at the part that mounts the bar to the bracket. IMO if you got in a hard crash these would rip right off.

Cusco makes a nice heavy duty R/S/B for the FD. It is threaded for the bolts that are going to secure the rear harness straps and even comes with the hangers installed for your trunk cover. Think I'm going to have to get that one!!
