Its done!
Here's a quick before pic when it had the 16s:
And the afters:
Doesn't look a lot lower, but I guess they still need some time to bed in and 20mm was never gonna be a big drop anyway.
But I'm well pleased with them. Don't really like cars that are too low, and with the miles I'd doing I need it to be comfortable and go over speed bumps with ease!
And to finish it all off some pretty good MPG on a 100mile trip
Need to get tyres soon, so will be downsizing to 215/40 instead of the current 225/45's this will bring the overall wheel diameter back to the same as it was with the 16s which will be good cos the speedo is way out at the moment. And the lower profile will probably look better.
The other plans are to get my sideskirts painted and fitted, and get the wheels refurbed - thinking anthracite like the photoshop a few pages back, but not 100% sure! Opinions welcome!
