I would like to get the CF roof as well. Would be nice to have some type of quick release to remove and install it easly.

 

also, looking forward on that fuel system

 

I'd love to see them make a 3 piece replacement so the sunroof would still work.

 

Yeah but I'm not sure about that, I don't think you would save as much weight as just replacing everything, remember the frame, the rails, motor all that weights too, and the whole reason for getting the roof is to reduce weight, the more you reduce, the lower the center of gravity of the car.

 

I'd prefer having the open air than worrying about shaving off 30-40 lbs. I'm sure losing the glass alone would be at least 20 lbs.

 

^^The reason for my wanting to have a quick release would be to remove the roof all together on those sunny days that I wanted to have the top off. I would just throw it in the back when I took it off.

 

t-top supra style? lol not a bad idea for a DD or weekend car but then you would have to work something out with some type of deflector, wind noise is going to be incredibly uncomfortable.

try holding the deflector down with your hand when you are the highway, and it's going to be something like that...

also, totally not trying to be an A S S here but, we shouldn't be threadjacking... this ptuning car and all the detailed information they are posting is very important.

 

When your exhaust is the loudest thing on 4 wheels along with an open WG.....I think wind noise is the least of your troubles....

We aren't thread jacking. Topic is about Ptuning's fabricated roof, and how they went about securing it to the car.

 

Thank you for eveyone's feedbacks, comments, opinions, etc. We thought about running the car without the roof, but the opening would create a lot of unecessary drag on the car.

If you can afford it, just ge the CF roof, especially for a DD, since the fit and finish would be more on par with the factory setup. Our aluminum roof is all about functionality (reducing excess weight on top to lower the CG).

Here's a few pics of the energy suspension bushing and motor mount bushing. These will probably be replaced with solid aluminum bushing at a later date. And there's also a pic of our air filter airbox/dirt shield.

Looking good everyday.

 

hey Mr. C, you guys allow people into your lab to see how things are coming along?... Might make for a great reason to take off of work and drive 2-1/2 hours!...

 

hey guys... are you still running 5x100 bolt pattern? have you guys tried fitting an xb2 on them since they have 5x114.3 and you would have a wider range of wheel choices? i ask cuz im not sure if they are direct swap or a little bit of tinkering will be needed... cuz if they are direct swap, i might have to do this and get a better selection on my next wheels.

 

We've thought about this since the new XB2 came out. The only problem right now is that we've got so much on our plate to get the car ready for the first race. We will need to get a hold of an xB2 front hub inorder to test it out. The other issue is that we currently have Stoptech BBK on the front and this would mean we would need to build a new aluminum rotor hub with the new bolt pattern or modify the existing rotor hub--not that we don't already have enough custom parts on the car already.

We will definitely look into this for the winter. Of course we can possibly build one from scratch--CAD/CAM, but it's going to be expensive This conversion--if it fits--will definitely be for die-hard racing only, because it's unlikely that anyone is going to spend the money and time to convert to the 5x114.3 setup and have to upgrade all their hubs, rotors and possibly calipers/adaptors and drive shaft to make it all work. But we might be lucky and it bolts right up.

Awesome Set up

 

Any idea on how much weight you saved by shaving everything and replacing it with aluminum? Kaminari claims the CF roof shaves 46lbs off the top of the car.

Also, do you plan on putting the car on a scale after it's finished and track ready?

 

With the aluminum roof on stop of the factory steel roof frame, we shaved 41 lbs of the roof.

We will be weighing the car once Seibon sends us the CF hood and rear trunk lid. Also Progress is building us a custom TA coil over setup with shorter springs in the front to allow us to run more negative camber with our existing wheel and tire setup. Once we get these parts in, we will weight the car and at the same time corner balance the car on our intercomp racing scales.

Did you guys finally get the Corner Balancing Machine setup ?

 

Yes, what coilovers are you running?

JIC magic Coils. I will email Mike so I can set something up

 

Nice sap when did you get the Jic?
