** Please note that your RST Race Suit will be shipped with the In&Box airbag module. Upon receipt and confirmation that you are happy with your suit's fit, you must register your airbag system, and choose either a subscription or one time purchase to activate it. We here at STG recommend the Revolution subscription with In&Motion, as it offers a lifetime warranty and enhanced support from In&Motion.
One deployment algorithm is included with the initial subscription/one-time purchase - additional deployment algorithms are available at a surcharge. To select Track Mode as your included mode, you must input your suit's serial number during the signup process, which is located on an In&Motion tag found inside your race suit. (NOT the In&Box's serial number) Click here to see more info, or to start the In&Box registration process.

RST V4.2 D30
Suit fits perfect! did my subscription for the In & Box air bag and now I'm ready to hit the track!! Figuratively speaking of course.. Thank you again STG!!

Tighter than version 1
I have the V1 of this suit. V2 is really nice but the D30 armor is thicker and eats up much more space. RST did not change their patterns for the new liner so it is much tighter. V1 was perfect fit 6' at 162lbs. My neck and shoulders were so sore as I fought to look up while in the tuck through turns. I had to put my old suit back on as I could ride properly. I will have to really stretch this thing out before I attempt to ride in it again. I think I can get it to work?? Be warned.

RST V4.2 Review
Just got the suit a couple days ago and the construction is top notch. From the stitching to the liner and the feel of the materials. It is everything you’d expect from a premium suit but with a better cost. The only issue I had was registering the suit with In&Motion. The explanation was that some of the newest RST suits did not have their serial numbers loaded into their database yet and so during registration the serial numbers was rejected and I could not activate the airbag system. After calling their New York support office they got it resolved. Overall I am excited to use this on trac next month! I did find the fit to be slightly small compared to the size chart and ended up getting a medium, size 52. I am 5’8” and 175 lbs. I found the 52 fit nicely everywhere except the arms feel a bit tight, so hoping those wear in a little bit or I may see about alteration just to loosen them up a tiny bit. Otherwise, definitely recommend this to anyone on the fence. Previous suits I have had are from Alpinestars and Sedici and I would say this is comparable in quality to the Astars, if not maybe even a little nicer.
