T1S-S07 Mod-Twin 225 HD Rigid Street Kit blends easy pedal feel, smooth but positive engagement with quick shifting for high powered AWD’s by combining twice the organic friction surfaces with a no-nonsense rigid Mono-Drive hub in a completely modular design. Each diaphragm spring endures an exclusive four-stage heat treating process. Steel-backed Friction Plates with high quality organic friction materials deliver stable friction coefficient, good heat capacity and long clutch life. These Friction Plates uniformly transfer torque to a Mono-Drive chrome-moly hub which is heat treated for strength and durability extending input shaft life with one continuous spline. The lightweight, rigid design allows for quicker shifts and trouble-free service. This kit includes a CNC-machined and dynamically balanced flywheel, pressure plate cover, diaphragm spring, face, puck-style ceramic friction plates, rigid Mono-Drive hub, floater, patented Monoloc Collar, release bearing, alignment tool and pilot bearing (if needed). Mod-Twin clutches are fully rebuildable and most components can be ordered separately.This Part Fits:

Great multi-purpose shirt...from the office to a night out
Color: Black, Size: Large
First impression, it is a great shirt. I was hesitant to purchase because of sizing concerns...products from them and similar brands tend to be too slim fitting for my taste. However, this shirt appears to be true to size, well at least American sizing. I typically wear a large and this one fit almost perfectly. Both neckline and length are perfect...can be tucked in or worn untucked. I am looking forward to wearing it with a blazer for a business meeting. It will also be great for a night out when I visit my favorite tropical vacation spot. I will definitely be buying more.
