I'm going to make a set of 951 front bumper shock deletes and can't find info if they are the same as NA shocks so I can make multiples. Can anyone confirm?

Well, the rears are obviously the same.

Part catalog shows two different part numbers for fronts.

951 505 015 00 impact absorber

944 505 017 03 impact absorber

Being that the body shell is the same at the location where the flange bolts to the chassis, I'd assume that's it either a) end to end length from flat mount flange to bolt eye or b) a dimensional difference at the bolt eye width, each of which could be made adjustable to fit both by design.

Unless your billet replacement keeps the fluid controlled compression, making a functioning replacement that is lighter, I don't see why these would be desirable. We just relieve the fluid by drilling a small drain hole, then mount them in a chop saw and cut away the entire housing and piston leaving minimal weight at the fronts. Don't even bother at the rear since that's where you always end up needing weight on a lightened car to attain correct F/R. By "correct", I mean tweaks that make these cars corner optimally.

I'm machining a set for a 951 owner. I made many sets for the 928 that removed 9 lbs total weight for fronts. I also made a lightweight set for my V8 converted 85 NA, now if I can only find that drawing lol...

Those look different than the NA shocks, i don't have one handy to measure for you unfortunately.

They are Definitely NOT the same.

That's what I recall. I remember moving the thru bolts back an inch or so to get the modded NA bumper recessed for TPC's smoothed bumper.

Has anyone drilled/lightened the 951 alloy bumper insert?

Pretty sure UK cars don't have fluid shocks, But there collapsible. Not sure on weight sure an eBay seller could tell you

I now have a factory 951 set on hand, so I'll be making a billet set shortly.

topley

definitely report back on the weight savings...

I have factory ROW non shock part. I can tale a picture & measure it if you want..

The alloy bumper itself can shave a few lbs. by drilling also.

Don't mean to be rude, but do you have any thoughts on the safety ramifications of what you are doing by drilling the bar and putting non collapsible ends on? They are there to absorb impact and to save frame rails in the case of an impact. Again no disrespect intended.

Voith

Row bumper mounts are non collapsible.

Looks like you are disrespecting Porsche....

No fret, I've been disrespecting Porsche for many swaps and upgrades.

Looks like 6 lbs getting tossed with just the 951 shocks....
