How to swap a TourX to Sportback front bumper

2018 Regal TourX
I’m trying to get this de-cladding over the finish line, and today I attempted to install a regular sportback rear valance onto the TourX. I considered ordering the easy to swap Opel/Vauxhall part from Blitzparts - but I’m still not a fan of the fake exhaust ports nor the cost of shipping this part from EU. So for half the shipping cost, I took a flier on the complete sportback valance after making some preliminary measurements on a sportback at a local dealer. The rear bumpers match in measurement in the center (edge of reflector to edge of reflector). The sportback does have a slightly taller rise from the edge of the wheel well to the corner - so it’s not a direct swap. But with some small mods, I got it fitted up today. I let the valance go from inside to outside midway down the corners. I may cut that later on - but for now I’m going to get a shim and drill a small hole in the bottom of the rear bumper behind the wheel and use a body fastener to snug up. There’s a lot of double stick across the top. FYI the sportback has reflector housings in the bumper (vs on the valance for the TourX) so those are held in with 3M double stick tape. It’s a little colder today, so I’m not thinking the tape will adhere super well (which is why I have all the painters tape holding it right now). I do think it will ultimately work with a little more fitting and tweaking. If that’s the case, I will put some exhaust extensions to the two openings and have the dual tips visible, which I would prefer. 03AEC367-71D0-465C-ACF8-96F0064C3054.jpeg F6713542-0414-4D86-9C5C-7E97D71A1701.jpeg D83DD745-B20C-4D3E-A945-CA1E4792FD39.jpeg

It looks like Real McCoy. Nice job. 🔨

EU specs rear bumper on the secondary market are not that expensive. However, freight/shipping is very expensive plus there is no assurance that it will arrive intact.

yeah the shipping costs are crazy. I understand it as the boxes are so large - but man, when it costs $250 to ship a $100 part, things start adding up fast. At the point we should get a group buy together and bring in our own container ;)

Kudos to going forth with testing the unknown. I thought about the Sportback rear panel as well and while visually they looked almost identical in dimension I just wasn't confident it would be close enough to risk. So just I forked out for the Opel center since I was going to order the matching rear skirts anyway.
Your version looks cleaner as it removes the chrome fake ports and allows an actual exhaust to be shown which I do miss.

Thanks - it’s fun to try different ideas. I actually do like how this one turned out (vs a solid “meh” on my plasti-dip of the wheels). As it’s getting cold now, it’s hard to work outside or in my non-heated garage - my hands don’t operate as well and these types of parts don’t flex as much. However I do think I can get this one to fit better - and I’m looking forward to getting some extensions to poke out the back.

I'm leaning toward the idea of painting the fake exhaust ports a satin black and installing white LEDs in them as better reverse lights (that should help illuminate the area seen by the backup camera) and they to alter the exhaust so I can use the Trans Am style splitter exhaust tips behind the rear wheels. The exhaust shop I go to is pretty creative in making things like this happen. We shall see. If I can't, then a pair of Magnaflows and some tips out the back may have to be other option. (Following your lead here)

I do think with a heat gun and well placed screws/pop rivets, the bottom corners can get nice and flush. Is the top of the center section tape only or are there clips that line up and snap into the bumper like the TourX?

I got this Rear Bumper Rubber Cover Guard for under $7. Great quality for the money. They come in a couple of different colors.

agree - heat would be a great help - I may play around with it this coming weekend to get it better adhered. As for fitting, there are 8 tabs across the top - of which 6 slide right into the existing openings without modification. The two tabs above the PDC sensor need to be cut down to fit in the slot. The PDC sensors also need something to hold them into the valance - and a quick part search number on the sensor reveals the Silverado uses the same sensor with a snap in retainer...I could only find grey color in stock (a little black trim paint makes that easy) but I have to imagine there is a black version out there. Drilled a 1” hole using a brad point (with wood underneath to create a clean hole) and then filed out the edges to slide the retainer in place. The two vertical tabs on the valance that slot in behind the wheel wells need mods. The top tab stays - but the groove for the first tab (on the bumper) to be extended upwards about 2” (I used a rotozip). The lowest tab can be cut off and smoothed with some fine grit sandpaper (wet sand works best). Moving forward I will sand the edge profile down to something thinner to see if the transition from inside the groove to the outside of the groove can be made nearly invisibly. However the other route is to cut the bottom corner of the valance to match the bottom edge of the bumper. It floats in space - so it’s hard to make heads or tails of where the cut would start and end on the valance and if it would look ok. Again, I will start with the first method to sand that edge down and avoid cuts. A shim with a hole in it should allow the body fastener to pass through the bottom of the valance, through the shim and into a newly drilled hole on the bottom of bumper. Rivets would also work - but as I have some leftover retainers I will try this method first. As I type all of this I again realize why YouTube instructional videos are so damn practical!!!

I am in the process of (maybe) converting to the Sportback front end a la the white example shown in this thread a few times. My front end got wiped out by a rogue driver switching lanes, so this could be the time if the body shop approves my modifications. In looking at this thread, I did not see a part number list for the Sportback mods, so here is the list I compiled. Hopefully it helps folks in the future. I have not included the OPC trim components from Europe.

Too bad that GM chargers core fee for old bumper cover. Eiter you will pay an extra $75 for Core Charge or you will need to give up your old bumper cover and return it to GM. I decided to pay $75 and keep my original Tourx bumper cover since it is worth more than $75.

Just a fyi, when you order a bumper cover, it includes the tow hook cover so that'll save you about $40.
The fog lights themselves are the same, just the outer bezels/chrome inserts are unique.
For the side skirts/rockers, you only need to order the first 2 PNs as they come complete with all the clips and covers. You can reuse the mounting screw from the TourX.

The tow cover is good to know. I was swearing at my computer about a $40 piece of plastic. Same with the $90 fog light inserts...

My car is in the shop and has been de-cladded. The bumper and rockers have been ordered, but we will see about the delivery timeline. I am going to have to leave the lower cladding on the rear bumper until I can figure out how to handle the replacement. IIRC, you can't remove the cladding and have the exhaust housing remain in place. Eventually, I would love to splurge on the Euro OPC stuff...
