Question:

Answer:
The Bilstein Heavy Duty and Sport will both work with your Mazdaspeed 3 without any modifications. The Heavy Duty is a good performance shock that strikes a compromise between sportiness and comfort on the street while the Bilstein Sport is an all out performance shock. Both will be a great improvement over your stock shocks, it just comes down to how much stiffness you are looking for. You can see those here:

I have installed the Bilstein HD on my 2007 Mazdaspeed3. I should have gone with the Sport Series because the HD’s shaft is 1/2 inch longer than stock. Sport Series would have been identical to stock. I don’t feel a difference in ride quality and think the HD works, but the Sport Series is the one for the Speed3 because it is lower than the regular Mazda3.
The Bilsteing shock itself is thicker and better quality than stock. It installs without issue.
