The H&R 29102-2 is a set of four progressive sport lowering springs for the second-generation (8J) Audi TT quattro and TTS quattro, the all-wheel-drive models. It is a direct replacement for the factory coil springs and is designed to work with the original dampers, so you can lower the stance and firm up the handling without replacing the whole corner assembly. Owners on user forums report that the wheel gap closes noticeably while ride quality stays close to stock, though a few describe a slightly firmer feel over broken pavement. The manufacturer's German-built, progressive-rate design is the main reason to choose it over cheaper generic lowering springs, which often trade comfort for drop.
Choose this set if you want an H&R-engineered alternative to a no-name spring kit, particularly for a daily-driven quattro that sees occasional track days. Searches for "Audi TT quattro H&R sport springs 29102-2," "8J TTS quattro lowering springs," and "TT MRC compatible lowering springs" are the typical buyer queries. Installation is a straightforward spring swap, but the manufacturer says alignment must be rechecked after any ride height change, so budget for an alignment.
The product is sold as the MRC version, and owners on user forums report running H&R sport springs on MRC cars without any coding. One forum thread questions how MRC responds to a lower ride height, so confirm compatibility with the manufacturer before buying.
The manufacturer states that the springs fit the same way stock springs do. If a spring is the same diameter at both ends, install it with the closer coils facing up; if it is smaller at one end, match the orientation of the factory spring. Front springs are marked VA or (F), and rear springs are marked HA or (R).
Yes. The manufacturer advises checking alignment after any ride height modification and bringing it as close to factory specification as possible.
This is a moderate-difficulty job that requires a suitable spring compressor, and owners on user forums say the rear springs are the hardest part to remove and reinstall. The manufacturer recommends measuring ride height before and after installation, from the center of the axle to the lip of the fender, so you can document the change. Confirm the orientation and front/rear markings before assembly, and schedule a wheel alignment once the car is finished. Owners on user forums also note that the stock dampers are not designed for the shorter spring, so check the ride and handling after the first drive.
