Hi all.
Am modding this bumper for a smoother look, reducing that top lip.

But at the lower edge, it is lower than the bodyshell.

This is normal for the 1.1 car? Should it it be reduced? Perhaps use the moulded air dam as cutting line.

Thanks for posting this. i have the same question. All the 94 luminas with smooth bumper on my builds, that lower part is sitting on the ground and i didn't even lower the chassis. the 90-92 kits the lower part of the valence is essentially in line with lower body line. I have a feeling Monogram Revell f'd up that bumper mold and made it too tall. I put two pictures here with both a real 90 era and 93/94 era luminas the 94 just looks smoothed out and not any taller.

I hope you post more details about how you are able to get rid of the lip as i currently have a 94 kit trying to figure out how to do that. was recently at the Hendrick Musuem and they have several luminas on display. thats when i notice how there is no lip and have been trying to figure out how to make that go away.

Thanks for the quick reply.

Am thinking to putty and sand the Lumina wording, sand down the air dam lip smooth and then remove 3 to 5mm of bumper.

A harder fix is to have the bumper sitting horizontal to ground. On mine it is pointing upwards slightly,so needs pulled back somehow.

And your Dupont car, the 94? No Lumina logo below grille.

Perhaps Monogram bumper is deeper just to locate that logo?

THe pictures are not my models. they are of the real luminas on the Hendrick Museum / Gift Shop

I've always found it is easier to TRIM OFF material ... than to have to ADD IT ON

[Vdc]

Some more shaping on bumper sides, making the front more narrow.



Sanding horizontal and vertical. Vertical with a taper, keep the bottom edge flared out.
And that top lip above grille, am sanding also a taper. Attempt to make that front end more aero.



Putty on the sides, yet to dry. See if I can later shape this correctly.

When I have a razor saw I'll trim about 5mm from bottom.

I really like what you're doing with this. Not going to lie, probably going to rip off your idea on my next Lumina build. Thank you for posting this.

Yeah do it!

I also recently learnt that these kits are based on the prototype NASCAR Lumina. After the kits release the car was reshaped.

And this pic of Earnhardts car, the superspeedway version?

The steep angle of the hood, that low bumper height. But see how much it juts outwards of the headlights.

Sawed off 4mm from the bumper and an immediate improvement!
Got rid of that cowcatcher front end.



Car looks much sleeker, though will need some card to round off wheel arch at rear of bumper.



With these mods it may also need a slabside, unsure as yet. This'll be in my dehydrator now, shrink the putty down faster.



Moderators. If you think this post should now be in Fab Shop, I agree!

[Lionpride]

Looking real good!
Thanks for posting the pics.

That's a great photo. Plainly see how narrow in width the top lip is.

Corners are well inboard of the headlight outer edges.

[LastoftheV8]

Here is comparison straight from Monogram kits of 90-92 Lumina front end vs 93-94 Lumina. You can see that the 93-94 is substantiall taller than the 90-92 which confirms my theory.

[Lionpride]

Are the after-market resin 93-94 front bumpers any more accurate than the kit one?

[Scotty]

lionpride,

No they are not accurate. They are molded after the yellow Labonte kit bumpers. I have ordered a set and compared on my workbench, and you can clearly see how they just used the updated kit bumpers to make a mold and then made resin "updated" bumpers. Nice quality, don't get me wrong. The usual quality we know from Mikes, but they are the same.

[Vdc]

Two pics to compare these bumper heights.

This #17, looks close to the kits design.



And in this photo of Earnhardts,how much forward that top lip pushes outwards. Looks like you could sit on it! And overall is a much sleeker shape.

[Lionpride]

I may try and CAD one up and 3D print it.

I'm working on the Lumina bumper fixes myself and thought I'd throw these pics up. It's all kit bumpers, a strip of styrene, and a lot of Mr White Putty. The rear quarter add-on to the bottom is a little bigger than I wanted but I don't feel like messing with it anymore. I got the rear bumper looking more like the 93 and 94 style. Still have some finish sanding and small patches to repair but I'm fairly happy with it. I don't mind doing the conversions but I wish the putty dried faster. It's taken me over a week just letting everything dry, sand it out, and adding more putty.

Looking good.👍

From the side, does your bumper point upwards? Something to check over.
Mine does, the Kelloggs kit. And it really makes for a clunky looking build.

I'll glue a strut inside somehow to level it, don't want to slice into the wheel arches.
