As a first foray into Tuning by the exhaust company Eisenmann {link} their Spark Eight is certainly a good start. High quality body modifications are well crafted and subtle; the front spoiler, brake cooling ducts and rear diffuser follow the form of the Audi R8 well whilst the new springs and dampers combine with the 8½x19" wheels to offer a sportier yet not extreme stance and ride.
Naturally Eisenmann offer a selection of exhausts for their Spark Eight which include the centre exit version that fit their diffuser perfectly.
For those who would rather benefit solely from Eisenmann's exhaust experience there are options that fit the standard Audi R8 rear as well.
