ASM Tuning’s catalog on Extreme Power House emphasizes model-specific styling and performance parts — not generic bolt-on bits. You’ll find high-quality carbon fiber exterior aero (pre-preg and dry carbon), interior carbon trim pieces, and performance exhaust hardware (notably application-specific downpipes and sport-cat options) targeted at specific BMW chassis and select Mercedes models.

What ASM actually sells (product highlights)

• Pre-preg & dry carbon exterior aero — front splitters, bumper trims, grilles, side skirts, rear diffusers, and trunk spoilers offered in pre-preg or dry carbon finishes for specific models. 

• Interior carbon pieces — center console replacements, carbon center panels, and dry carbon seat-back covers / interior trim pieces for model-matched upgrades. 

• Carbon mirrors & small trim — replacement carbon mirror housings and smaller exterior trim pieces sold per application. 

• Performance exhaust hardware (downpipes / sport-cat variants) — model-specific front/downpipe options (sport-cat and application-matched downpipes for S58, etc.) to pair with exhaust/upgraded tuning paths. 

• Full carbon body kits & large assemblies — complete, model-matched carbon body kits and multi-piece aero sets listed for certain platforms. 

Model coverage & examples

ASM listings on the page include parts for a range of modern BMW chassis (examples visible: X3M/X4M, M8/8-Series, G-series M cars, etc.) and select Mercedes models — each product is shown per-application so buyers can confirm year/chassis fitment before ordering. 

Buyer tips (accurate & practical)

• Always confirm exact chassis/year fitment — ASM parts are often model-specific (many items list the exact chassis and fitment).

• Check finish & shipping — some items are offered raw (unpainted), pre-preg/dry carbon, or painted — product pages show the available finish and price.

• Downpipes & local rules — ASM sells sport/downpipe options; verify emissions/local regulations and whether tuning is required after install.
