Non-Convertible vs Convertible

00gtCoolGuy · November 9th, 2007, 12:13 AM

so let's say two completely equal GT's would go head to head...regular vs convertible...what's the 1/4 mile difference between the two? is it a huge gap or drivers race?

weems · November 9th, 2007, 12:21 AM

drivers race bro , equal drivers then obviously the coupe has the edge..

wrong........

convertibles are way less areodynamic and weigh about 2 hundred lbs more.....

there about half a second slower then coupes

With top down they are way less aerodynamic. With top up its the same. They are just heavier.

yeah, i've heard of around a half second difference...that extra weight has to play a difference....what does the average convertible driver run stock?
i know the coupes do about a 14.1 - 14.5

well if your going run the 1/4 alot, then a coupe b/c for a vert i know you have to add a roll cage which would add more weight but if your just making a cool street car then i would go with the vert. my .02

just get what u want. My vert out runs most coupes in town, I would trade a half sec any day just to put the top down... iIplan on swapping to a 5.4 this winter if i can afford it and I will put custom full length sub frame conectors and in cockpit tubular conecters then triangulate the the under carage. just to be safe... it will add more weight but it should help it from twisting on me. my point is get what u want then mod it to do what u want

RyanGT · November 9th, 2007, 03:52 PM

I love my vert! Just need to find a good roll cage now... Want to get some track times, and know they would say get the hell out after one run...

Wrong......

The verts are less aerodynamic then the coupes. A coupe will go faster, top speed, then a vert even if they weighed the same.

How so just curious? The top doesn't flop around or anything. And wont be that noticeable of a difference...

Something about the air moving over the convertible top vs. hard metal roof makes a difference.

The extra weight is from all the extra stiffening that the convertibles require, because since they don't have a roof, they need more support underneath the car.

RyanGT · November 9th, 2007, 06:37 PM

Yeah i knew the weight thing, just not the aerodynamics. Learn something new everyday! But still thats not a huge difference when you start actually modding it.

00gtCoolGuy · November 9th, 2007, 07:58 PM

lol, i already have a coupe...i ran a 14.3 my first time out so, i know what i can do, but my buddy is looking to get a vert, just wanna see how much of an advantage i have

JASonic · November 9th, 2007, 08:44 PM

Drag. A vinyl top has more drag. There is more friction with the air than a smooth solid metal top. Even the smallest disruptions will have some effect. And no, it does not flap at all. Its very tight when you maintain it correctly.

I will say this though. the "sensation" of speed is alot greater with the top down and the windows down. I love my vert. I wouldnt have it any other way.

I have to agree with F02Vert. I would give 2 or even 3 seconds for the vert. Since I dont race ( cuz this sucker is slow anyway), I really enjoy cruising with the top down... and it looks good doin it!

My coupe was built on a vert frame so where does that put me?? should I make it a hard top vert???

+1 for you too.... but i still love my non-vert... all opinion,.. but i think it looks cleaner

StangAddiction · November 10th, 2007, 07:46 PM

im partial to coupes...I wouldn't buy a vert becuase im not a fan of verts and i dont like extra weight. But to all thier own. Im not a "top-down" kinda guy and I've always thought coupes look a lil cleaner so i'd take the coupe. In the end, a vert GT is probably no heavier than a cobra. I've always looked at it that way. When you buy a cobra you make a weight trade-off. When buying a vert you're doing the same. There is more drag, but that kind of drag isn't a huge issue until you're running 100+ mph. Basically its like having an extra passenger holdin small parachute out the window.

+1 It's not a huge weight or aero difference, but it will effect the performance of the car a little.
