I have an 06 R/T Charger and I am contemplating getting a set of Eibach springs for it. What other costs might be associated aside from installation? What other products would I need to purchase, if any?
Thanks for any input,
Well son, there was once a time when lowering springs ruined the suspension settings of a half-assed platform: hat tip to my dear Fox Body Ford. Hopefully your German-bred Chrysler product has none of those problems.
Eibach makes two kits for your car: spicy and spicier. That’s because the lower you go, the more heat you gotta handle.
Lowering (or lifting, for that matter) springs alter any vehicle’s suspension geometry. A wheel alignment is mandatory, and the LX forums seem to agree. Mild lowering kits (1.5″-ish max) are usually fine with stock dampers, even if a firmer shock compliments a lower and (usually) firmer spring. More aggressive setups usually need a matched set of dampers to go with, unless you care not about ride degradation.
Sometimes a full suspension kit includes an anti-roll bar upgrade too, which could help the feel and scrub understeer but the reduced left-to-right suspension flexibility isn’t necessarily that fantastic. More jolts don’t translate into faster lap times: do extensive research before you buy.
There’s also the matter of stock wheels: even the R/T might look a little silly with a lower body and boring-ass stock wheels. A bigger rim with a shorter sidewall is needed to “complete the look.” A different offset rim (see hyperlinked thread above) can also help with the inevitable: the meeting of expensive rubber with metal body parts. And brings me to the big problem with aftermarket lowering bits: driving style!
The more you have, the more likely you’ll avoid the punishment of potholes, pavement joints and puddles. If you live in a place with bad roads, or flooding, you might want to reconsider. Because nothing’s worse than a sore back, a tired ass and a hydro-locked motor if you treat a lowered car like a normal one.
Bonus! A Piston Slap Nugget of Wisdom:
See the slippery slope here? What exactly do you want? Looking lower requires more parts than just springs to complete the look. That’s the stance or hellaflush look, and it ain’t cheap. Going faster for the road and track? Going full aftermarket may be overkill: I’d try some factory funded engineering perfection via SRT-springs, famously high quality dampers (like Koni, Bilstein) and stickier tires on stock wheels. That won’t make you look any cooler, but you certainly will be.
