Hey guys I was wondering how much a drop I would get with Vogtland springs, on a Sport suspension 2000 A4 1.8T Quattro? The guy I am looking to buy off said his drops with 1.4, and I told him that I have sport suspension, and he said that it should drop more? Can anyone give insight on this? If it is true or not? Thanks guys!!

A popular suspension modification is replacing the stock springs and shocks. Sometimes this is done to get better handling performance, sometimes just to lower the vehicle, and sometimes to do both. But often it's unclear what the data and specifications in the ads really mean.

The B5 came with a standard suspension that produced a ground clearance of 4.3 inches. An optional sport suspension was available with shocks and springs designed for better handling at the expense of a softer ride. The sport suspension lowered the vehicle by .75 inches (actually 20mm), giving it a ground clearance of about 3.5 inches.

Popular aftermarket springs lower the vehicle even more than the sport suspension. However, the lowering numbers listed in the ads for them are almost always based on the stock non-sport height. Here's the data for the commonly used springs:

H&R Sport Springs lower the car 1.25" in the front and 1" in the rear from the stock non-sport height or .5" in the front and .25" in the rear from the stock sport height.

H&R Race Springs lower the car 1.9" in the front and 1.5" in the rear from the stock non-sport height or 1.15" in the front and .75" in the rear from the stock sport height.

Vogtland Sport Springs lower the car 1.5" from stock non-sport height and .75" from stock sport height.

Vogtland Club Spec Springs lower the car 1.4" from stock non-sport height and .65" from stock sport height.

Eibach Pro-Kit Springs lower the car 1.4" in the front and 1.3" in the rear from the stock non-sport height or .65" in the front and .55" in the rear from the stock sport height.

WARNING: These numbers apply only to quattro AWD B5s. Numbers for 2001.5 MY B5s may differ because of the redesigned spring perches. Check with the manufacturer or your vendor to confirm.

The problem with lowering the vehicle is that the resulting reduced ground clearance may result in increased damage to the vehicle undercarriage due to debris on the road. Only the stock non-sport suspension, for example, can be counted on to get the vehicle safely over a 2x4 laying on end. Another problem with a lower vehicle is a reduced approach angle which may cause the front of the vehicle to scrape on driveways, speed bumps, etc. (or the rear of the vehicle if going backwards). You'll also risk bottoming out sooner in deep snow. Before you lower the vehicle, think about how this will impact your driving and repairs.

If you want performance without significant lowering, you have two choices. You can install coilovers in place of the shock/spring combination. Many coilovers are height adjustable. You can also install a performance shock with your OEM springs, sport or non-sport.

Fwiw I have the vogtland sports on stock sport struts and it was definitely an upgrade over stock sports. Both in performance and aesthetically. It probably lowered the car a half to 3/4 of an inch over stock sport height. I love the way the car rides and handles but I wish the car were a little lower, like race spring height.
