Hundreds Of Products Ready Today. Dispatch/Collection The RS2 saves cockpit space; the RS7 feels more enclosed
Both are serious head-restraint shells. The RS2 has the slimmer outline, while the RS7 brings more pronounced upper-body containment and asks more of the cockpit.
A 5ft 10in driver with a 32in trouser waist can sit in both, as our showroom photos have shown, but that does not make the choice interchangeable. Shoulder height, helmet position and the space around the upper wings decide it.
Trouser size does not show hip shape, thigh size, torso length or where your shoulders meet the shell. Seat dimensions are a useful filter, not a substitute for sitting in it.
Try them with helmet and normal racewear
Settle the pelvis against the back pad and check the shoulder openings before looking at head-wing clearance. The helmet needs usable space, while the torso still needs firm support. Make sure the thigh bolsters do not force the knees into an awkward pedal position.
Head wings often clash before the base does
Map the door glass, cage, B-pillar and roof opening around the upper shell. The RS2 is useful where a full head-restraint seat must fit a narrower cabin. The RS7 needs its extra external space checked at the actual mounting height.
Use the exact seat and support documents
Read the physical approval label and current Mirco instructions. Confirm the side mounts, lower-belt slots, shoulder route and any FHR requirements with the event rule set. Do not transfer measurements or brackets from another Mirco shell by assumption.
Let the driver choose, then prove the shell fits
The RS2 is our starting point for a tighter cockpit or a driver who prefers a less enclosed upper shell. The RS7 earns its place when the driver benefits from its shape and the wings clear the car. Neither is an upgrade over a seat that fits better.
RS2 and RS7 questions
Is the larger RS7 automatically more comfortable?▾
No. Extra room helps only when the driver needs it. Too much space reduces lateral support and can put the shoulders below or inside the wrong part of the shell.
Can I rely on the published dimensions?▾
Use them to rule out obvious problems, then measure the actual cockpit and sit in the seat. Padding and body shape change how the internal space feels.
Will the same side mounts fit both seats?▾
Check the current seat drawing, mounting pattern, approved supports and vehicle kit. Similar-looking shells do not guarantee an identical installation.
Should I buy the seat before planning the harness?▾
No. Seat openings, driver position, belt route, anchorages and any FHR use need planning together.
We can compare the RS2 and RS7 in the showroom
Send hip, waist, shoulder and seated-height measurements, plus the narrowest points inside the car. Better still, book a seat test with Garreth or Cameron.
