Monogram Corvette C4 Roadster (Geiger Widebody style)

Recommended Posts

Hello modelers,

I started a new project this year after the model show in Jabbeke/Belgium on March the 11th and 12th. Even thought of joining the CBR with this one only for fun building. It should become part of a community build for the next FFM meeting in October 2023.

Inspired from achieving the 3rd place in the US customs / Lowrider category for my 2021 Cannonball entry I wanted to do some refinements to this old Monogram kit which is IMO more detailed then other kits but still lecks on some points. First it should become a standard conertible only with a few 80´s style mods. Not to mention that my mind changed during time.

IMG_20230312_143028.jpg.b75b311fc78311f7ef273a0887918f7a.jpg

Lets begin...

First of all everything started as always. Sorting parts, try to get missing parts, etc. Taillights are still missing but I think I have an idea for them.

If anyone can help me with the turbo setup parts from the Callaway speedster would be fine. I´m willing to trade these for the non turbo parts of this kit.

IMG_20230318_162740.jpg.59c657611872e546a75f491858e07617.jpg

Then the brain started working or maybe not. Don´t know anymore. In fact I cutted out the convertible top deck lid and hinged it. I´m still thinking of a working top but we´ll see.IMG_20230317_182526.jpg.b220a030dfc098f84bb1508c596f82f8.jpg

IMG_20230317_182458.jpg.6e259aa8f1e5a323e7c0b3653ec68493.jpg

After that the molded in pedals on the interior tub went away and were replaced by selfmade padels out of styrene.IMG_20230318_122031.jpg.fbfef787c0d4556e1f28d1083831f209.jpg

Then I thought about building new front turn signals and running lights. They were made out of different stripes of styrene, covered with mirroring foil like I did on my last build and at least got lenses out of clear plastic from the parts tree.IMG_20230319_173206.jpg.e78cdf22332ce93e83bf1e6cba9cfd84.jpg

IMG_20230320_181344.jpg.d1bec8993e5e3cb4dd8e7d6789e540a4.jpg

Meanwhile they´re gone and th whole nose is cutted in pieces...

Last step for this first post will be the gas cap. I cutted out the complete area and scratchbuilt the inner parts...IMG_20230321_190246.jpg.b34349ff1f8836af9c965bf4920e756c.jpg

IMG_20230322_175518.jpg.e67955c99490d724a5bbde5c69f57d0d.jpg

Therefor the rear mounting point of the interior tub had to be changed but that I will show next time.

Will be back for more soon, Rico

Thanks guys for the positve comments so take a seat and join the ride...

Part 2 - The conversion begins

First of all I searched for the wheels and tires needed for this project. Found nothing, so I decided to draw and print my own. Here´s the first attempt.IMG_20230416_183252.jpg.38d4bacdfb3b306008f5075e587c61cb.jpg

After having done these I started the bodywork. Closed all the lines around the body with 0,5 x 1mm evergreen.IMG_20230417_204702.jpg.3aa7deebc2439924d41cd806d25699b6.jpg

Then tubbed the rear fenders with a sheet of 0,5mm styrene with mostly the exact wide as support for the following steps. Then started building steps on the rear end.😂IMG_20230423_162315.jpg.de387b3b5ef3e6b78f24af8ff0ac6c8b.jpg

IMG_20230423_162326.jpg.ec94f52cc5e4410aceb049c847303eec.jpg

First try of sanding them into shape looked good enough to encourage me to go on with it

IMG_20230423_170556.jpg.522c27fcf2b3f225fedd100192313e87.jpgIMG_20230423_171154.jpg.805b49e8840bd8496a5bca9a8fa08fc3.jpg

One day later I rised the marked area for more accuracy...

IMG_20230424_200043_edit_54723237633832.jpg.c4fafef96547e3b9a6f2165480dcfea7.jpg

IMG_20230424_200107.jpg.bcaf12f81e0c3d122d0134f35e918115.jpg

During the next days the rear fenders took shape step by step.

IMG_20230426_202704.jpg.b92d489b48261b47bc9cf80b0bb24ec3.jpg

After the first rough sanding the fenders looked like this.

Hi guys, thank you for your positive conmments. Now here´s

Part 3 - more bodywork to come...

The work in the following pics took about to months (not every day but continously)

First started the widening of the drivers side door in the same way I did the rear panels. Built steps and gave them a roughly first shape.

IMG_20230501_180228.jpg.e0970c6a4f483748f6c5a3c816315374.jpg

IMG_20230501_180312.jpg.8b9ba359f8720dca65fa58f06fcf1e0e.jpg

IMG_20230501_180320.jpg.178d4ef4d6f7cfd63533a20b6d240851.jpg

Then refined the shape for the first time.

IMG_20230501_210548.jpg.47230a48ff137d408482a0904f0b8857.jpg

Next step was lengthening the nose also by adding sheet stripes.

IMG_20230624_204647.jpg.5cb5cff49e631f8164d5750c915162e1.jpg

Soem filler primer on the nose to see how it looks and the strated the drivers side hood. It´s already pretty much in a rough shape.

IMG_20230625_202218.jpg.5c88e9d106a9618d08eccbf735df50e6.jpg

IMG_20230625_202237.jpg.a648ae227b4a0e80ed84871caf06c56c.jpg

Then refining the contours again and again.

IMG_20230626_204739.jpg.184a803e4cc27c4756892bd8c49d9632.jpg

IMG_20230627_193948.jpg.33fd2487c739ecad42de0dd5079b5ed2.jpg

IMG_20230628_195813.jpg.9fc0796eabdfbda5f0dc8652ff723d54.jpg

Then I did the air vent behind the front wheel.

IMG_20230630_204844.jpg.9db2bdc13570c84fe4c7c0e6ac1dc021.jpg

IMG_20230630_204910.jpg.078615b271fa117dac47090da9ce939a.jpg

Next step was doing the air intake in front of the rear wheel and the side skirt.

IMG_20230630_220248.jpg.b0d56f08b650992d23b1a0f757b73ec3.jpg

IMG_20230630_220307.jpg.919d0ddc8c9c6858ff820427f89147f0.jpg

IMG_20230701_164152.jpg.d42c6daef301aeae5ecd39c589d669a4.jpg

Last but not least an additional piece of styrene for the nose to follow the line of the hood.

IMG_20230703_073521.jpg.27c4ac57aeaa513054ce4e0291e2b6e9.jpg

Stay tuned for the next update, Rico

Just spectacular watching your build! Is this an actual car you are replicating, or something out of your imagination? Either way, too cool!

i think it might be the roadster version of this one    https://www.automotive-auctions.nl/en/offer/48429-luxury-sports-and-classic-cars-in-boxmeer/chevrolet-corvette-c4-geiger-57-v8-1992

This is one of the cars I use as reference. Always liked this widebody style since I saw it for the first time back in the early 90s.

Verkauft Chevrolet Corvette C4 Cabrio ., gebraucht 1990, 68.000 km in  Cuxhaven

Pic from: https://www.autouncle.de/de/d/127307102-gebraucht-chevrolet-corvette-c4-cabrio-original-geiger-zr1-bre

Meanwhile the bodywork is mostly done. Will show some update pics soon.

Also found the biturbo engine from the Callaway kit. 1000 thanks to kelson who sent it to me without charging anything.

Started already to strip of the chrome and mounting the engine.

Stay tuned, Rico

Thanks guys, I really appreciate your positive feedback. So let´s go on to

Part 4 - more bodywork and engine started

First some mockup pics with wheels and windshield...

IMG_20230706_102552_edit_447457265569727.jpg.ed7bdd7bd36931c8318a7bab22281172.jpg

This view I like the most.😁

IMG_20230706_102615_edit_447411550519213.jpg.e0d39ad72c61a92b4d43c94b04bbc0a6.jpg

Then some progress pics from the bodywork on the passengers side. Built steps again...

IMG_20230707_211631.jpg.87f3079919d8cf34b38bf815af4463f9.jpg

and grinded them into shape...

IMG_20230716_192454.jpg.f7b9b280adf7d2ba6238c167afd841ca.jpg

Then again the air intake in front of the rear wheel...

IMG_20230719_193831.jpg.b77b88f5edca81dab218af4fae5a857d.jpg

and then the side skirt and the air vent behind the front wheel...

IMG_20230720_185440.jpg.0f4af048d90b552b6f79b4ed6d6d44f2.jpg

IMG_20230720_185518.jpg.d44dcbcca10aea33bde596b4367ad246.jpg

A good view to see if the overall look of both sides is close enough ...

IMG_20230720_185631.jpg.fd8c439284b953cdec8334ce5ed0b4e0.jpg

Because my own deadline is Oct, 13th this year (Friday before the model car meeting in FFM) I started to paint and prepare some engine parts.

First the intercoolers from the Callaway speedster kit with photo etched clamps added.

IMG_20230723_121919_edit_540785386822149.jpg.e876d0164a1b81c6fec99c56f17f183f.jpg

Then dechromed all the plated engine parts except of the valve covers. Did a little cleanup on the intake manifold parts but cleaned up to much because I grinded away the smaller diameter pipes which I first thought would be flash from the injection molding process. Done some new pipes out of 0,64mm wire and mounted them with a little block out of styrene. Not 100% accurate but I can live with how it looks.

IMG_20230723_200516.jpg.3cb49bf0e7570aa0c20d5f30ec152855.jpg

Finally some color for the block and manifold. Because of it should become a crazy 80´s-90´s tuning style car I´ve choosen some crazy colors.

IMG_20230728_175511_edit_562493828189668.jpg

Stay tuned, Rico

Since you started this thread I've been gifted an 83 Corvette kit my brother had no intention of building.
Though I won't go such an extensive route as you I will use some of your processes.
Thanks for posting.

This is body work school! That is some very cool work, Rico. Can't wait to see where we goin'.

Thanks Jim, I hope to get the bodywork done soon because all the other things need attention too.😁

Outstanding sculpting only superseded by your keen eye, Brother! -KK

I started a pickle fork that would go good with your wide body C4:

Your boat looks terrific. There´s as much amount of bodywork in it as on my vette. Very nice. I really like the idea. Can you post some detail pics of your bodywork? Would be glad to see these here.
