M3 owner looking for a change

Evening all,



I've been driving M3's for the last 6 years and I'm looking at S5's as a possible alternative. All of my M3's have been mildly modified to bring out more of the available performance, induction, map's, exhaust, suspension & I’ve been told that the S5 offers similar options.



Ideally I’m looking at an S5 cab with DSG



Questions;



Sensible engine upgrades (£5 budget)



What needs to be changed with the suspension & brakes to cope with the changes in performance?



Ive driven a coupe & cab and the exhaust note didn’t make me smile, any options that you can live with every day whilst still making me smile



Does the DSG box cope with performance upgrades?



Any help is greatly appreciated



Cheers



Tyrone
