Okay, seems to be a lot of talk about wheels so I'm throwing this one out there... we'd love to see our 20" Taglio on a Vantage and are prepared to knock $2000.00 off the price for anyone who's prepared to provide some good-quality pics for our website and post on 6speed. These are usually $5500.00, comes with the usual array of colour/finish options.



Very Bad Photoshop:

 

Yeah I agree you shouldn't need wider rubber with chip plus exhaust, but you could get some lighter wheels in stock sizes which will help by dropping rotational mass. In my case, the larger wheels are lighter than stock, as are the larger tires.

 

I have been eyeing those concave ADV 1 - the 5 spoke and the 10. according to the member on here they are 19lbs a piece.

 

Tahoe, saw that you finally got your HRE's. Let us know when you get to weigh the oem rims

 

Awesome thread. I recently was reading up on sprung vs unsprung weight and I'm excited, because I ordered a set of 20" forged wheels, which should be lighter! I ordered them because I loved the look of the new wheels and didn't specifically realize I could gain a good performance advantage as well.

This leads me to a couple of questions:

1. Are the 19" 5-spoke sport wheels forged? (I didn't see it stated in this thread)

2. Was it indeed confirmed that the front wheels are 21.7 lbs and rears 23.9 lbs?

3. If the new forged rims are say 3 lbs (per wheel) lighter, will that significantly affect handling?

Also just to be clear, we're talking about these wheels, right?!?

 

Yep those pictured are the V1 sport pack wheels and are forged as are the V2's.
Hard to say exactly what the gain is, I've found with both my Astons and previous cars on forged alloys they feel more stable and the steering improves. They give you A LOT more confidence in the cars ability
Though going up to 20" you will lose some of the gain.

 

When you say going up to 20" I will lose some of the gain, can you explain? I thought larger rims (20") would help improve handling?

 

You are adding higher density weight (metal) increasing the wheel size even if you keep the same diameter
Adding width will give you more grip (and more weight again!)
Increased weight at the hub (unsprung weight) adversely affects handling as well
This is one reason why motorsports don't use big alloys with low profile tyres.

Over the years I've spent WAY too much on alloys and eventually worked out small & light is best.

 

Oh! Yeah, totally get that... actually the 20" rims I'm getting weigh the exact same as the 19" stock sport wheels I currently have, so no additional unsprung weight. The widths are the same too so no real extra contact patch for grip.

I meant will the 20" size impact the handling just because of the size? I've heard the ride is more bumpy with 20's because less rubber "cushioning" effect, but does the additional 1" add any turn-in quickness, etc?

 

It's a factor of rotational inertia. 20" wheels will have a greater concentration of mass further away from the rotational point leading to greater inertia. I can go into more detail if you wish but simply put, this is one of the major reasons why.

 

Yep that's another problem with large wheels

 

Does anyone know the weight of the front and the rear V12 Wheeels ?
This model :

 

I would like to know how much these weigh?

 

@Kanga
Very light, nice.

Does anyone know the weight of the front and the rear V12 Wheeels show in the picture ?

 

Does anyone have any idea what the OEM 18" wheels weigh? I like smaller wheels because I'm weird (they're lighter of course). The GT4 ones are a little busy looking while the original sportline or whatever are pretty attractive IMO (as are my stock 19"s).
