H&R J-Stock Turner Motorsport Race Spring Set - E30 - (NO LONGER AVAILABLE) TURNER3000

J-Stock Turner Motorsport Race Spring Set - E30 - (NO LONGER AVAILABLE)

These "J-Stock" racing springs were the class-leader in the days of the popular J-Stock class of BMW CCA Club Racing but we have been using them in almost every E30 racecar. These were originally modeled after BMW Motorsport's spring set for Group N racing in Europe. Now made by H&R we have spec'd these springs in a progressive rate in the front up to 680lbs and the rear up to 1026lbs. This makes them over twice as stiff as H&R's own racing springs and a better match for true racecars used for club racing, time trials, autocross, and more. We set the handling balance for the full "J-Stock" suspension to have a very slight tendency to understeer based on feedback from our fastest customers. These lower a stock E30 M3 by 1.5" and 1.25" (front/rear).

Although you can buy these springs as only a set, we strongly recommend installing only with our special Bilstein shocks at the same time.

This item fits the following BMWs:
1984-1991 E30 BMW 318i 318is 325e 325es 325i 325is M3
