Loving my GT Vantage but I would really like to go up to 20” wheels.

Had some great advice on this forum from a V12 owner and I am now looking at Forgeline GS1. However, I am still struggling to understand the best width and offset for my particular car.

It looks like the GT has a slightly different set up as standard to the V12 so it’s tricky to compare the geometry apples for apples.

I am looking for an OEM look with only a very slight offset.

Using the calculators online and some OeM data, it looks like the following might be a good size but I’m not 100%.

Does anyone know if the -6mm reduction in clearance on the inside (front and rear) is going to be problem on the GT?

Original
8.5x19 ET50
10x19 ET60

New
9x20 ET50 (+6mm and -6mm)
10.5x20 ET60 (+6mm and -6mm)

Thanks

 

Why not just get OEM 20" wheels? Someone local has a black V12S and went from 19" to 20". At first, I thought that was his car in the picture. Does the local dealership have an extra set of wheels? When I had my Vantage they had a few sets of used wheels as I was going to buy a set for winter tires.

 

I have 20's with Michelin Pilot Sports on my vantage with the sport pack suspension. It is a very stiff ride. While I like the looks, stance and ride, my wife doesn't like harsh ride. I wouldn't have this set up for a daily driver

Correct me if wrong, but AFAIK there is no such thing as "OEM 20" wheels" for the Vantage; all OEM wheels were 18" or 19".

OP must be very lucky with the road quality where he lives. I find the roads have gotten so bad in most areas now that I would never plus size. FWIW I think the OP's car looks great in the attached photo, and would be a bit closer to perfection with about a 1/2 inch of drop, and with spacers to sit the wheels out maybe another 1/2 inch or so.

 

I had 20" on my 2015 GT - Do not have the offset information (I bought them used)

 

I think you're right on that! He said 20", but did not say from which model when he told me.

 

Just got these, custom made.

front 20X9 ET42 Michelin 255/35/20
rear 20x11 ET52 Michelin 305/30/20

been using DB9 20 oem wheels before with same tires, no issues at all. I have sports pack suspension too & lowered with Velocity Springs 3/4 inch all corners.

 

Those are sharp and have an OEM look them. Would have no idea they were not factory.

 

I kind of copied new V12 vantage wheels.
Wanted to stay with OEM look. Just waiting for new center caps with engraved Aston logo.

 

this looks great - thanks for the info. I asked and there was no 20” OEM wheel for the vantage of my year of car.

I also agree with all the comments on ride and this is a watch out for sure .

 

yes, old gen vantage didn't came with 20's. I had DB9 oem 20's for awhile before I got theses just about 2 weeks ago.



DB9 20inch oem wheels 8.5 x 20 front 11 x 20 rear

 

20"s fill out the wheel wells well. I have spacers to increase the stance. Still have my SportPack wheels which are best looking wheels for the Vantage

 

Thanks for all the suggestions.

I decided to keep the wheels and try out some 11mm spacers.




Fills things out just enough for me.

 

looks nice especially with the yellow calipers
