I've been thinking about how the aftermarket is going to modify the body of the car after I noticed the GR Corolla H2 Concept had a noticeably wider body than the standard GR Corolla, pictured below.

So what about an aftermarket widebody kit? The front fenders would be easy enough since it is replaceable, but what about the rear?

On most cars, rear quarter panels have to be cut to gain enough tire clearance to wide body a vehicle. I know this from experience on my other vehicle.

However, the GR Corolla appears to be unique. Not only is it widebodied from the factory but also the overfenders appear to be replaceable. Notice the seams in the following pictures:

How are these mounted to the body? That's a good question. I found some hard-to-find angles of the door. The overfender piece on the door appears to be mounted by three screws. I would also not be surprised if it had adhesive.

How about the rear quarter panel? Finding a good angle was difficult, but I did not see screws on the inside of the door jamb. It is possible it is mounted from within the fender well. It is significant, however, that the overfender appears to be its own piece:

So what could a widebody kit from the likes of Varis or Rocket Bunny look like? They could very well be non-riveted overfenders that mount to factory locations and a rear bumper to match.

Why is this a big deal? You can wide body the car and still be able to reverse it to stock body!

@Guff, you should take a good look at those overfenders when you next get the chance.

More forum detective work! Good catches.

I think the car looks wide enough from factory, but I also understand the desire for more wideness. The more we look into this car, the more it seems like Toyota really did design it for the enthusiasts.

This is assuming that they are easy enough to replace, but this would also be great for any fender benders or accidents on track. I hope they are removable and replaceable. It's tough to confirm without seeing the car in person.

I would think it's just some adhesive and screws. Sadly for the rear bumper it looks like it's just part of the bumper itself and not tacked on

At least it won't require cutting up the metal! It is possible the seam seal the inside to prevent water collection/rust on the inside.

Would be neat to have a clean method for wider fenders.

The riveted/exposed bolt look is really tacky/gaudy (ala Rocketbunny), IMO.
Hoping for a possibility for a factory aftermarket widebody from TRD Japan. 😂

Wishful thinking probably.

I’m hoping with GR becoming bigger, Toyota would go back to the old days of making a bunch of stuff for the cars. Lol
Like TRD? Be careful what you wish for! There was a time back when that TRD parts was good, they had springs, cams, transmission gears, LSD, etc. Now?

Well the bumper cover is a cover, so conceivably aftermarket could make an entire cover assembly with the correct mounting tabs. more expensive and a pain to ship (not much more than fenders), but clean.

Alternatively could the aftermarket kit not make a piece to go over the flare on the rear bumper? Use double sided tape for the top and rear and attach the rest by doubling up where the existing skin bolts on?

It's the same with STi. I have a whole catalog at work for STi performance parts from the early 10's/late 00's. Has strut braces, shifter knobs, short shifters, entire brake and strut upgrade kits, body kits, steering wheels, exhausts, etc. Nowadays you get a cool STi badge on a plastic piece that looks like carbon fiber to protect your door cups.

I'm a pretty big fan of widebody kits and look forward to the kits people will undoubtedly make for the GRC. But before jumping on the widebody kit I do wonder how big of tire we can run with aftermarket wheels. Regular GRC gets 235s and the Morizo gets 245s.

I've got a thing for meaty tires. I'm already trying to see if I can fit 275s square on my foxbody.

If its a separate piece then I expect there to be a number of clips and copious amounts of adhesive. Very possible that it has studs that are bolted in from the backside as well. Would be very interesting if it was replaceable; it would make rear quarter repairs potentially much easier and less costly.
