Hello, I've got a problem that I'm hoping someone will be able to help me out with by sharing either advise, a picture, or an exploded diagram. I've got a new front spoiler for my 1991 928S4 and have the spoiler install kit (from 928intl #928 505 071 21 KT) but when I pulled the old spoiler off none of the 3 metal brackets in the kit were on my car (it was held on by bailing wire .) I've searched my own 928 archives, PET and the WSM but can't find a good pic of where the 3 metal tabs go? Any pics, advise would be better than me guessing. Thanks in advance.

 

They will go from the rear of the spoiler to the metal tabs that are under the radiator. I installed a new one a month ago and sorry I didn't take any pictures.

 

Cool, that helps more than you know. Thanks Sean!! Joel

 

Sorry guys, either I'm not that bright or there is a piece missing. I still have the fans out from my TB project and was putting this spoiler on while I'm waiting for a torque wrench (that goes to 218 lbs) but I don't see where the brackets bolt up to? My car is missing the belly pan but in looking at the radiator, there are two places where these brackets might connect to but they don't reach the rear part of the spoiler?

 

Here's a quick shot of the one I installed.

G'Luck.

 

On your '91, there are three metal tabs spot welded on the bottom of the oil cooler (this cooler was used starting in MY '90). Those three spring tabs screw onto those tabs and the spoiler is screwed to the other end.

 

I don't think these tabs are welded - I think they are rivited. But they break off quite often, and you can't buy them separately from Porsche. Maybe, if there is enough interest, you can get them from Hooked On Cars in the future. Anybody interested, please PM me.

 

Here is a pic, it's not the greatest since I had to reach under the car and try to get the angle.

As you can tell, I used a tie wrap in the middle due to not having the mounting kit.

What looks like rust under there is actually the leaking orange coolant from my devek radiator.

Also, I have no idea if there were any changes from MY "88 to yours. There are other holes that the belly pan screw into, as you can tell, mine is not attached.

 

My '90 oil cooler is missing those tabs, and my plan was to rivet replacements (home-made, of course). But there were three obvious places where each original tab was......well.....spot welded. I began prepping to drill them out to receive rivets, but decided not to risk going up into the lowest tube running across the radiator. PO hit something that broke the spoiler and put a significant upward crease in the cooler. I was surprised it didin't rupture that lower tube, but everything works okay. Anyway, perhaps some of them were riveted, but not the case on mine. I wound up bying three wire harness clamps which were placed on the round tube running just behind the cooler, and with strategic bending, got the springy pieces screwed into place. Works well. If it weren't an ordeal, I'd shoot a pic - and will do so if anyone wishes.

 

Argh!!!! Thanks guys, now it makes sense. The factory oil cooler was replaced on my car by the P.O. with a fluidyne unit which is in a different location. Looks like it's fabrication time. I'm sorry that I didn't think about that earlier. As always, thank you all for the info and help!!!! Joel

 

​​​​​​Does anyone know the bolt sizes that hold this rear portion up. Apparently I lost them all and now it's sagging.
