So we all know there is 3 key ingredients to making a car fast, weight reduction, big power and traction. The lighter the car is, the better it handles (usually) the faster it stops and the faster it goes as it does not require the same amount of power that a heavy car does to get going.
Since I’m in the crazy weight reduction phase myself (you can read my current weight reduction methods here) I’ve decided to compile all my research regarding lightweight parts that you can buy on this page.
I’ll be adding to this page in the future as I compile the weight comparisons of different parts.
Let’s start with racing seats:
R100: 26.9 lbs
Chrono Road: 33 lbs
R505: 34.6 lbs
R700A: 35 lbs
R700P: 35 lbs
Out of the reclining seats that Sparco sells, the R100 model is not only the cheapest seat money wise, but it is the lightest weight recliner that they sell.
Fixed Back Seats
Speed2: 16.8 lbs
Fighter: 16.0 lbs
Out of the fixed back “street seats” available from sparco, their Fighter seat is the lightest weight option.
Competition (Fixed Back Seats)
Sprint V: 18.7 lbs
REV: 15.9 lbs
EVO: 12.6 lbs in carbon fiber
EVO: 19 lbs for fiberglass version
Pro 2000 II: 19 lbs for fiberglass version
Pro 2000 II: 13.7 lbs carbon fiber version
EVO III: 19.6 lbs
EVO II US: 19 lbs
EVO II: 19 lbs
Corsa: 20.5 lbs
Circuit: 21.2 lbs Fiberglass version
Circuit: 13.5 lbs carbon fiber version
Pro ADV: 24.8 lbs
Circuit II: 24 lbs
S-Light: 13 lbs
The lightest weight competition fixed back racing seat from Sparco is their EVO carbon Fiber version seat which weighs in at 12.6 lbs
A4: 26 lbs
CR1: 27 lbs
LG1: 26 lbs
TRS: 27/28 lbs depending on the width of the seat
VX2000: 32 lbs
GTS II: 27 lbs
Sport Seat: 29.5 lbs
Moab: 24 lbs
Baja RS: 28 lbs
Baja XRS: 27 lbs
The Moab seat is Corbeau’s lightest weight reclining seat.
Forza Sport: 26 lbs
Sprint: 17/18.5 lbs depending on seat width
Pro Series: 19/20.5 lbs depending on seat width
The Sprint is the lightest weight FIA seat that corbeau carries.
Fixed Back Seats
Classic II: 21 lbs
Classic Bucket: 15 lbs
Clubman: 18 lbs
FX1 pro: 19/20 lbs depending on seat width
Pro Series: 19/20.5 lbs
Forza: 19/21 lbs depending on seat width
RXP Rhino: 16/17 lbs depending on seat width
Baja XP: 23 lbs
Baja Ultra: 16/17 lbs depending on seat width
Baja SS: 15 lbs
Baja JP: 17/18 lbs depending on seat width
Baja low back 17 lbs
The Classic bucket and the Baja SS seat are the two lightest weight seats that are offered as fixed back seats from corbeau. I’ll admit, the Baja seats are an off-roading suspension seat, and it suprises me that they are that light. This makes me question possibly putting them into the race car that can be somewhat of a harsh ride at times with rod end suspension and crappy roads.
