shorter overhangs and lower hood
 
2 Attachment(s)
I much prefer short overhangs and low hood lines. I like the red concept car very much. It is cleaner than the FRS concept, with an S2000-like hood line.


Why didn't they produce that beautiful concept? Did they get caught out by some hood pedestrian crash standard? The sheet metal hood lands above the chassis look added on to me.


I mean, if you have such a low engine, shouldn't the car lines reflect that instead of looking like a normal engine installation?


Anyway, I'm going to modify mine when I get it later this year to shorter overhangs and a lower hood.

Don't you just end up with a hard top Miata if you do that?

I love both current and 2nd gen 86 silhouette.

the amount of metal and plastic fab to re-do the front end has got to be about 5 years worth of spare time work.. it's going to be easier to just chop off the front just ahead of the firewall, and build a tube frame with custom sheet metal...

Buying one of these will save considerable time and money:

I would love to see how OP intends to achieve this without ruining the car, or costing tens of thousands of dollars in sheet metal and bodywork. (I don't think OP understands what would be involved here)

HKz 03-01-2021 10:11 AM

The twins already have quite short overhangs...way too much work for a rather minimal change from the side view...and good luck making the bumpers look good after smooshing them in.

Top tier professional designers & engineers vs flybo2160...place your bets folks

This reminded me of a couple abominations I've come across on the interwebz like this one..

He just needs to carefully push the car into a wall from both the front and the back.

Dont worry about the cracking and crunching sounds...those'll buff out hopfully when he's reached the desired overhang. And if the bumper falls apart, just 3d print new ones.

Its so easy, why havent the car designers thought of this???

I kind of wantta see how this goes.

I'm planning on butchering extra front and rear plastic body panels. I'll reuse as many portions that attach to the car as possible to avoid, as much as possible, fit problems. The remaining areas will be fabricated using Rutan's layup over foam technique. I'll foam an oversize glob of foam in place, trim it to shape, then lay up fiberglass over the foam and remaining pieces of the stock parts. The excess foam is then removed. I have the composite fabrication skills to do this.


I'll probably do the same thing with an extra stock hood.


If the new car has structure similar to the existing one, it looks like there is open space to shorten the plastic front and rear bumper covers.

Dake 03-01-2021 01:07 PM

I'd argue that the twins have about the same overhangs as the S2000 already.

That being said, if you are able to actually integrate it as smoothly irl as in a quick photoshop, it could look pretty interesting.

Overhangs are fine wit me. In fact a "proper" FR sports car is generally going to *want* to have longish rear overhang for better front/rear weight distribution.

What I wanna do is section out 10" of the lower part of the car and shove the rear wheels forward 10". Should be easy enough with a Sawzall, no?!

Funny enough this could work. A friend once "accidentally" jumped his Gen 1 Durango at Silver Lake Sand Dunes and face planted the landing. Somehow the airbags did not detonate, but the entire front end was mildly squashed. Luckily, it hit squarely and the damage was almost symmetric and didn't actually look like damage. The fenders and hood gained a subtle increase in the curves and the bumper was a little more flush. Aside from replacing the condenser and radiator he never had it fixed because he thought the result left it looking more aggressive.

Not saying I'd try this with an 86 twin, but I'd definitely enjoy watching the attempt.

flyboy2160 03-01-2021 02:43 PM

Lololol How do you guys know what engineering and composite fabrication skills I have? Lolololol We’ll take bets when I do this next year!!!

This all depends on the new car having a similar structure to the current one.

My plan is to modify just the plastic bumper covers and the hood. I’ll remove the rear bumper and perhaps replace it.

IF the new car is similar to the old one, there is plenty of room to reduce the overhangs, as shown below.

My plan is to reuse the areas of the parts that include the attach points and fabricate new areas in between using Rutan’s lost foam process. I’ll make oversize globs of expanded foam that are in contact with the saved portions. I’ll trim these to the desired shape, then lay the initial fiberglass plies over the whole deal. After removing the blob, I’ll remove the formed in place foam. There will be more fiberglass and of course, bondo and sanding and bondo and sanding.

Guys guys. I don't think we're paying enough respect to the anonymous internet poster's skill level. :D

Seriously though flyboy - I think you will get plenty of recognition if you pull it off. And I have no problem saying I'll follow your build thread. Until then though, it's all just dreamin'.

Do you have any other projects you've done where we could see examples of your handiwork?

Red-86 03-02-2021 12:51 AM

What an odd thing to be concerned about. The overhangs are already quite short, and if you want it to look lower, just lower it on some coilovers. The hood is already pretty low, about as low as you will get on a budget, front-engined sports car with today's safety regulations. Even with a boxer four, they still need to leave a certain amount of space between the top of the engine and the bonnet for pedestrian safety (and cooling etc).

No like at all. Looks ill proportioned, like a clown shoe. The roof now looks too high for the car since the car's overall length is now too short for that roof height. Nope.

PulsarBeeerz 03-02-2021 02:31 AM

Just get rid of the OEM strut style suspension and you can lower the hood as much as you like.

Really not getting the "clownshoe" references. I love the Z3 coupe, but my short-wheelbase BRZ surely is more similar in shape to 2-seat FR cars that have a more "normal" fastback/hatchback roofline like:
Z4 coupe, new Supra, Shelby Daytona Coupe, 250 GTO, 240Z, etc. etc.

The one thing that bothers me most about the FT86 is the 2+2 compromise. A *proper* FR 2-seat sports car generally has the rear wheels situated just aft of the driver, and not shoved way aft like a Scion tC. Functionally this puts more weight on the front wheels, hence we have a craptastic 55/45 F/R weight distribution. A short-wheelbase FT86 would be 50/50, would be ~100 lb. lighter-weight, be a bit stiffer torsionally, and would be even more responsive-handling. All wins for me. And I'm also a big fan of the look as well. Doesn't look "taller" to me due to shorter wheelbase, and definitely wouldn't in person.

If the rear seats were removed and the rear wheels moved up, would that not make for a higher F than R? Seems to contradict your hopes for 50/50. Or am I misunderstanding something here?

Indeed you are! Moving rear wheels forward puts them closer to the c.g., loads them up. That's why most dedicated 2-seat FR sports cars have the rears (and fronts) shifted forward relative to the driver vs. other cars. To get static weight on the driven rears. It's also why FF cars have the rear wheels shoved relatively way AFT. To unload them and keep the driven front wheels loaded.

Think if you moved the rears WAY way forward, at some point they'd take 100% of the weight and moving them any further forward the fronts would lift off the ground!

I do understand that, I guess I just misinterpreted what you were saying earlier. Because removing the rear seats would lower your R weight and also adjust the CG to be further towards the front. Or maybe I just didn't get enough sleep this morning as the little one decided it was time to be wide awake in the middle of the night.

Removing the rear seats plus other mass by sectioning out that part of the wheelbase in front of the rear wheels and behind the door would have a minor effect of F/R distribution which would be WAY more than offset by moving the rear wheels forward. But yeah, taking that into account distribution might go from 55/45 to 51.5/48.5 instead of the desired 50/50 or better. So maybe shove the front wheels forward a smidge as well! Rear wheels 10" forward, front wheels 2" forward, 50/50 on a 93" wheelbase ;)
