After recieving the MSM transkit myself, I can tell you that they repopped Museum Collection's wheel, then modified the spokes, essentially deepening the cuts torward the center to replicate the Stradale wheel. They also narrowed them to fit the stock Tamiya Modena tyres, Museum Collection made theirs wide to fit Tamiya racing slicks. The MSM wheel looks great but diameter is too small for Stradale.
The MSM seats are much nicer than Acu Stions.
The cooling scoops in front of the front wheel openings on the front bumper part, are not as accurate as the SAS front bumper scoops.
The Acu Stion decals are more complete including all Stradale emblems and gauge faces. The stripes on the Stradale are suppose to be the same width as the Ferrari emblem on the 360 engine cover, MSM's are a little too wide and Acu's are about right. MSM's stripes seem to be more opaque but a little less quality regarding the little green and red stripe. Any lack of opaqueness can be remedied by cutting some plain white decal to put under them.
MSM's work is good overall. The interior parts, body parts and decals are very nice. The supplied exhaust tips are not impressive though, seem too small.
