heloo all

ive rescently bought an astra coupe, but as usual my luck run out and i found it needed a new clutch and slave cylinder the day after i bought it privatley (bad times)! my mate fitted it for me today and the car seems to be running well . sooooooo as im new to the forum and modifying any sugestions would be greatley apreciated i was wondering what mods are good for a first timer, mainly performance but i think it needs lowering also

cheers Mike
