Question about front valence on 87 325is


#1

After a short off road excursion at RRR, my front valence took a somewhat downward slant. I pulled it straight enough for Barber, but it drug on the trailer pretty bad. I took it off to straighten the brackets and sheet metal behind it. Two questions:

  1. Does this welded diamond plate brackets look at all OEM ( I would bet $1,000,000 not)

  2. Does my oil cooler look ok? It pretty bent up, but not leaking. Should I replace?

Thanks for the advice.

Your oiler cooler is facing the wrong way… Other than that, if it isn’t leaking, and oil can circulate through it, it should be fine according to Geiger Engineering.

The front valance: Where did you get that jacket? [Jeff Spicoli quote… Answer: “The Network gave it to me”]… back on topic… I mean, where did you get those brackets?

I had the original factory brackets in random condition and finally they all bit the dust. I put two 10mm nuts and bolts through the aluminum bumper and the top of the spoiler and one 10mm nut and bolt on each side through the fenders. Yes, I know, the side nuts and bolts hurt my aero package for fast tracks, but at least they act as little tiny splitters? I will not win any concours events in my near future either, but it can scrape hard going onto the trailer and save me hours of frantic zip-tie-ing to ensure I make it to qualifying. Lastly, to take the spoiler off, it takes 4 10 mm nuts and bolts and maybe 5 minutes.

I’ll take a pic if that saves me from typing the remaining 804 words.

John,

BTR has a great solution to the train sweeper front valence (cheap too). Come see us at CMP for the set up.

Craig is spot on with the cooler adjustment, rotate forward 90 degrees and leave it alone.

You know I wondered about whether the oil cooler fins should face foward. Seemed strange for it to all be out of the airflow. I figured it got bent hitting too many curb stops.

I like your idea Craig. Those brackets, while a feat of modern engineering, are a little much. You have to appreciate the time that went into making them out of alumunimum bar stock and diamond plate. The welds look really good to.

John to improve on Craig’s set up slightly, run the bolt down through the bumper and put one nut on it and tighten to the underside of the bumper so the bolt is fixed in place. Then install valance and add a second nut to hold it in place. It will be easier to take off and put on if you don’t need to “hold the bolt” while tightening the nut. Also if you place the bolts where you can get to them through the driving light openings it should be pretty easy.

Or…

Shim the bolt with washers and then put a small piece of aluminum flat stock with a nut holding the whole thing on. This way you just have to slide the valence onto the lip of the aluminum and then bolt on the two end bolts. Two bolts/nuts and the whole thing comes off. All three BTR cars have been running this set up all year, very sturdy.

Come see it this weekend if you are at the track.

Thanks for the ideas! My 87is spoiler is rather droopy. Now I know!

Jumping the ditch at Summit didn’t help it…:unsure:
