OK so not massively impressive at the minute but still a work in progress. Here's my Mk4 Astra SRi. 30mm lowered with 17" Boss XTS wheels and Black Diamond drilled and groved disks, debadged with colour coded rubstrips and handles. Light smoke tints all round and Lumma LPC-R CC front bumper.
It's a 2.0L 16V and the only engine mod's are a Viper induction kit and lexmaul manifold.
Install wise I'm in the middle of trying to get a quality sound setup while ditching my sub!! So I have infinity Reference components in the front and for now some X-Plod 6x9's in the rear. Considering they are only ran through a cheap amp at the minute they give an awesome sound if you put the bass boost up slightly but still lack some punch for now.
Currently the PC is installed in the glovebox but once I am happy with my setup it will be moved behind the centre console and will be completely out of site. The GPS antennea sits nicely under the grill covering the two window blower vents so it's out of site. So hopefully once finished it'll be a lightweight minimalistic install that is capable of more than you'd think.
A future project I'm looking into is taking the 201Bhp engine and drive train out of a 4x4 Cavalier and putting it into the Astra. But that's something I'm looking into for next year!!
