I tried the search tool, except it throws anything out under 3 letters, so finding specific threads on the swap I want to do is difficult.

I have a stock suspension and have found a killer deal on a s4 suspension. Is it going to be a simple swap in swap out procedure? I have done a M3 suspension swap before so its not my first rodeo, I just g want to make sure there is no modifying or machining involved.

Oh also the price on the brakes is really good too. Will the S4 brakes fit inside the stock 16 inch rim? I would love some more stopping power especially cuz hauling the car down from some speed the other day to a stoplight was interesting to say the least.

 

I think it's a direct swap, but you can't lock your tires/invoke ABS with your stock brakes? I can.

 

I ran the S4 suspension (struts, springs, and rear swaybar) for a little under a year and loved it. It will only lower you a fingerwidth or so but the feel, control, and handling is a vast improvement - jump on it. It's a 100% direct swap with zero modification.

I don't know if the S4 brakes will fit the stock wheel but the A8 upgrade does. It's been on my car for almost 3 years and it's worlds better than the A4 setup. ECS Tuning sells it for $250 with vented rotors or $299 with slotted or drilled/slotted rotors. Hands down it's one of the two best mods I've made (along with upgrading to HIDs and projectors).

 

Don't get drilled rotors. Ever. Ever. Ever.
