Question convrt. weight vs. ...

does an 91 convertable weigh more or less than than its counterpart?

also is there a correct term for an rx7 with a hard (solid) top (idiot question.)


Edit: removed head bang emoticon.

it weighs more. goto www.mazdamark.com and check out the mazda rx7 vehicle specification sheets.
though its a debateable term, i call the hard tops "coupes." others may swear by "hatchback." i agree its a hatch, but i call anything (i can think of) with a hard top a coupe. also, mazda calls the 91s "Coupe" as opposed to GTU, GXL, SE...
dont bang your head against the wall, its not very becoming.

The S5 convertibles were the heaviest of all FC's in the US other than the turbo 'verts overseas.

So should I buy one with not that many miles on the engine or wait for a hatchback?

Depends what you want. Do like to drive with the top down and open air motoring? Or would like to save a bit of money and buy a regular coupe thats a little better performing. (handling and speed)

Not bashing the 'verts. I think they look very good and wouldn't mind having one with a TII swap.

I am looking at the coup, I prefer preformance over looking "cool"

now I think I will get (look) the turbo model.

Red face

not a bad idea, but the problem is the extra 200+ pounds will weigh the car down and reduce mpg, I recently just got a raise, but because of gas costs I can barely afford to fill up the camero I am driving right now. Bastard only gets like 12mpg gonna put it down like old yeller when I get the chance.

my car is such a worthless peice The door was rusted shut when I first got it. I needed to crowbar it open

FAWK, haven't been in the FC section for awhile, come back and there's like 10 threads about weight. The drop top FC's are heavy pigs! Nothing a little 20B or turbo couldn't help.

The FC is not a true coupe as it has a hatchback. A coupe has a seperate boot (trunk, whatever).

The heaviest factory RX-7 ever is the JDM S5 Convertible (which is turbo'd) at 1390kg (3060lb).

I have an S5 TII, and it's only like 70 lbs lighter... so verts aren't that heavy.... it just comes down to if you like verts or if you like hard tops...

Convertibles are really heavy if you want to make a fast 1/4mi car. Go FB S1 or S2 if you want a really nice power to weight ratio, you just gotta do a 13bt swap.

These are the specs on my Turbo-vert. The car can be seen with listed mods in my garage section here: https://www.rx7club.com/vbgarage.php?do=view&id=2592

The interesting part of the alignment results is the car still maintains a near perfect 50/50 weight distribution which many did not think possible after the conversion. It was weighed with 1/2 a tank of gas so it could be a perfect 50/50 actually with less fuel. It is a fat heavy bitch though...

Some basics: Battery relocated behind passenger seat under spare tire cover along with 2 amps and 1 subwoofer, spare tire removed, power steering removed, still have a/c, large fmic (front bumper support removed), Kirk Racing rollbar, full TII drivetrain. Car was aligned and weighted with the targa top removed and top down as required by any road race sanctioning body. 1/2 tank of gas. I weigh 165 lbs.

Final specs as requested by me...
Front camber: -3.0'
Rear camber: -2.0'
Total front toe: 0.06" = 10 min. toe in
Total rear toe: 0.06" = 10 min. toe in

Cornerweights....with me included of course:
LF (858 lbs)_____RF (799 lbs)-------->49.45%
LR (877 lbs)_____RR (817 lbs)-------->50.55%
Crosswieghts are exactly 50/50
LS total: 1735 lbs (51.8%)_____RS total: 1616 lbs (48.2%)

Total weight with me: 3351 lbs.
Total weight without me : 3186

I do have 382 rwhp @ 16 psi to move the fat pig around...and should be well over 400rwhp this time next month.

dude, your vert is bad ***, nice job though. I love my vert, and it's kick *** that the car can either be a targa or a convertable. my car isn't that heavy, and I've surprised a lot of people with it's performance

vert's are what people think they are

I live in Orange County and I drive a 1991 Convertible. It's a great car to drive-not too expensive to buy and with normal maintenance will last 200,000 miles. I get 16-19 mpg depending on how much I keep my foot in it. It's the perfect car for where we live and it's bigger and more comfortable than a Miata. Parts and good shops are plentiful and besides-you don't see yourself everywhere you go.
