What are the cons for removing the tray?
It hangs down abit and scrapes on bumps

have you tried puting the bolts back in. they often get pulled out.


keeps engine clean
nicer to work on engine bay as clean
improves air flow through rad
stops debris hitting some pipework
imporved mpg (only very very marginal but it will help)


takes longer to work on car
hangs down and drags when hit

Bolts are a bit of a pain. They are a wide flanged bolt. The original fitting on mine where a mix of torx and regular hex heads. I made up a full new set using Allen key head stainless steel bolts with stainless penny washers hot glued on to them. Works a treat. Can't remember the bolt size. M6 maybe?

AndyMac, I did similar to you.
To start with, the tray fixings just at the front of the two road wheels had rusted away, so I replaced the two wing supports that have hank bushs at the bottom of them.
Then I repaired the tray with aluminium sheet, pop rivets & glass fibre.
I then fitted the tray using stn. stl. hex bolts & penny washers. The bolts are M5, nine in all.

Ah, undertrays eh?

Takes me back to my Rover 75 days, undertrays that fell off on the motorway were a rite of passage.
