RaceComp Engineering’s classic Yellow springs offer an excellent combination of function and form for 2015 STI. With the release of the new 2015 twins, Subaru stepped up their game with an impressive chassis but left room for improvement. Following an in-depth evaluation of the VA suspension, RaceComp Engineering Yellow spring rates are an aggressive 365 lbs/in front and 360 lbs/in rear that match the new OEM valving on the 2015 STI. The Yellow spring set also retains more bump travel than competitior’s springs by including new rear bumpstops and a drop of 20mm front and rear. The goal was to minimize the understeer these cars have from the factory and offer a spring that not only performs exceptionally at the limit, but also retains ride comfort to daily drive around town. The result is a car that handles extremely well from corner entry to corner exit.

Spring rates:

• 365 lbs/in front
• 360 lbs/in rear

Lowering:
