I'm sure there are previous discuss on this so please give me the links on previously posted topics.
So, summer is coming so I'm looking to do the following mods on my 2003 2.5i Z4:
Summer tires: Michelin PS2 17 x 8 front and 17 x 8.5 rear
Wheels: SSR Competition
For a few extra horses I'm looking at:
Racing Dynamics Exhaust (they have it dynoed at about 6 extra ponies and I haven't seen other exhaust with dyno numbers)
Cold Air Intake filter
Shark Injector (but I haven't seen on for Z4)
For suspension, I'm looking at:
Springs and Shocks mixing and matching between various manufacturers.
Bushing replacement.
I've looked for brake kits, front and rear, but I haven't seen any for the Z4.
Now, I would like comments and suggestions on my ideas for this summer's mods. Any help I can get online and offline is much appreciated. Thanks in advance!

In all seriousness, you may just want to take the money that all those mods would cost and sell the 2.5 and use the difference to buy a 3.0 Z4.

If you want a killer deal on a supersprint, let me know.

The Supersprint exhaust would be a good place to start.
TurnerMotorsport has a Pulley upgrade

No Shark injector but Dinan's software claims to improve throttle response, if not power. http://www.dinancars.com/Series.asp?...%20Tuning#1292

Do you track the car and find the brakesare inadequate? Have you done Fluid upgrade, ss lines and pads? and lastly consider improving the cooling.
Unless you have money to piss away or really like the look of the big brakes- I think its unnecessary and alone may not provide any real improvement over the stock brakes with some better Pads, Motul or similar hi temo fluid and ss lines.
Then spend 30 bucks on soem red caliper paint,
If that not enough- get cooling help ala Turner plates and some 3 1/2 inch tubing.
