Front spoiler install
I just bought a front spoiler for my 86 off a forum member. Could someone send me a pic of install position. I haven't had one since I bought the car and it is so distorted that nothing lines up. I'm having the crack repaired today and would like to install asap. thanks

You sort of have to manhandle it into position. they warp really easily, but you can just bend and screw as you go. I can take some pics of mine this week when I've got the front end in the air, but you shouldn't need them. just bend to for the pre drilled holes. I believe some of the holes from newer spoilers don't line up on older cars, but there should be enough that do for a sturdy mounting. If you're nervous, you could probably warm the spoiler with a heat gun.

Pics here, but you MUST have the tray behind it as well, otherwise it will do no good and also will not be braced enough to stay in place. The tray fixes to the bottom of the air dam and also to the wheelarch baffles and the cross member. The dam top edge screws up with self tappers going into clips behind the body panels and to the bottom of the lower grill. These holes should be there, both on the dam and the body panels and match up. All together the dam and the tray significantly help high speed stability.

Did you notice on the first spoiler pic you mentioned that the horns have been moved to the side for cleaner airflow, and although not visible as it is above the panel, so has the secondary coil.

So, are you saying that the stock front bumper there is a relatively thin aluminum (aluminium) beam? Have you had a good look the bulky monstrosity they bolted to the front and rear of the U.S. models in the name of "safety"?
Yes, I did notice that, but, I wasn't sure if you had done that, or, if that was the stock setup over there.

I believe that the cooling marginality on the XJS is all about the lack of clean airflow to the rad stack; the slot and moving the coil and the horns, give a huge increase in uninterrupted clean laminar flow to the rad stack. The consequence of which is far better heat transfer than standard. Until you have unbolted the front bumper and tried it, it is hard for people to grasp just what a difference it makes to the speed of cooling down after, (eg) a hot traffic stop. I have a main electric fan, and it never cuts in, even in the hottest weather, unless the car is stuck in traffic on a really hot day after a hot run. (rant over !)

There are definitely a lot of things blocking airflow to the radiator, and the bumper is one of the major offenders. I plan to do away with the bumpers on JagZilla, and go with something similar to the nerf bar bumpers on a '65 Cobra.
This is what we have in the states:
I haven't weighed it (I could though, if someone here is interested in such things), but, it's easily 5-10 times heavier than what comes standard in Europe.
Sorry for the thread hijack BCXJS.
It might be worthwhile to start a new thread on the various versions of bumpers, as well as the procedures for modifying them, so that people can find all the info they need on them in one location.

I'm sure he's talking about the lower valance panel, which is completely hidden by the spoiler, but, is the body panel which ties together the two lower front corners, and creates the lower lip of the front grill opening. That part was at least 3/4 rusted away on both of my cars when I bought them. They pop up on ebay from time to time, and I think that I saw one in Paul's Jaguar ebay store a few weeks ago.

Part no. RTC1531 | Lower panel parts from Jaguar Heritage Parts UK
Amazingly, still available according to JCP ! The lower grille bolts to the top of it and the spiler to the bottom, I seem to remember. Just had a look and ther are a couple on UK ebay, eg: Jaguar XJS Front Lower Panel RTC1531. | eBay

There are 2 metal brackets that attach to the plastic wheel arch stone guards and the tray. I made new ones out of some SS strip and used some plastic nut and bolts to fix as the steel rusts...... I also put some small SS washers between the tray back edge and the crossbeam so that any water could run out and not re rust the crossbeam.
