| I decided to run Eibach
springs and Bilstein shocks on the A4. All it took was a ride in another A4
with that setup to convince me I needed it as well. There really isn't too much to
report on the suspension though. The car now handles like a champ, taking corners at
increased speeds with minimized body roll. The ride quality is firmer than a factory
sport suspension, but not harsh. For those of you worried about riding like a rock,
this setup is far from that.
The car now sits about 3/4" lower than the factory sport suspension, about 1.5" from the non-sport suspension. I left the perch setting at the default one it comes from the factory. There are grooves on the shock where you can adjust the ride height by moving a clip up or down the shock. For those with an Avant, you may want to try setting the rear perch down 1 from the default setting to achieve a balanced look. The car now handles and looks like it should have come. Coupled with larger wheels, the car has an "aggressive" appearance.

After literally 6 months of shopping I finally
decided on a wheel. I wanted something with a bit of a lip to it, and I also like
the look of a multi-piece wheel with rivets. Another requirement was that it had to
be big enough to clear big brakes as well. Price was also another objective. I
didn't want to spend more than about $500 for each wheel. As it turns out, these
ended up costing about $540 each. They looked good and met my requirements.
The ride firms up a bit more with larger wheels, but, the handling is greatly
improved. Turn in response is better, and I get better grip with the larger wheel,
even in rain. The tires I used to run were 225/40/18 Bridgestone S-O2s.
I have upgraded to 235/40/18 Bridgestone S-03s now. I can fit the
larger tires because I have rolled the fenders. If you want details
on that, go back to the main page.

|I debated over which brake to purchase for quite a while. I had weighed many kits, Alcon, Movit's Porsche kit, Brembo, Tarox, and probably others I can't think of. In the end I decided on the Brembo. This kit had some neat features I liked about it. First it wasn't nearly as expensive as an Alcon kit in a similar setup. Since price was a concern, I didn't want to spend 5000$ on a brake kit. The hats were designed to make the rotor "floating". The fasteners that hold the rotor together have some play in them. When the brakes get hot, they can expand evenly and pads can evenly clamp the rotor's surface. Another nice facet is that the caliper and hat are aluminum, so it is a big reduction in weight savings. I think the whole brake system for one wheel probably weighs less than just a stock A4 caliper. The caliper has 4 pistons and the cross-drilled rotors measure 328 x 28mm.|
Braking force is now
spectacular. I ran these on the car for about a week before a track
event. Track performance was stellar. Time and time again the
car stopped without fade. While pedal travel did increase slightly,
the feel did seem to firm up. Overall,
I am very pleased with the kit. I could go bigger, but not without
really digging deep in the wallet. The brakes also look good behind
the wheels. They nicely filled up the space that used to be behind
After a few track events
and driving on the brakes on the street I began to notice cracks in the
rotors. Cracks are common to cross-drilled rotors and are usually not
of consequence. Although the cracks I had begun to see were from the
rotor/hat bolt hole to other drilled holes in the rotor. My rotor was
beginning to play connect the dots. I replaced one set and after
awhile the same thing happened. These rotors are not cheap either,
costing $600 for the pair from Brembo. That is when I decided to run
slotted rotors instead. I called up Coleman
Racing and they were able to make a custom rotor for me once I sent them
a spare rotor I had. The price of slotted rotors from Coleman runs
about $300 for the pair which is a lot more reasonable in comparison.
The only extra effort involved is that you need to have the rotors turned to
get an even surface (cost ~$30). Here is a link for the specs
of the rotor, which Coleman also has on file as well.
