OE Volvo 240 TURBO, 1980 GT, & GLT 23mm Front 23mm Anti-Sway Bar.
Great upgrade for regular 240 which uses a 19mm front bar in earlier years. Fits 4cylinder cars 1975-1993, will not fit deep front-sump V6 and Diesel directly. Diesel is close, V6 certainly not. Saddle bushings in very good used condition, bar itself from a salt/rust free climate in good condition. New replacement polyurethane saddle bushings are available from IPD inexpensively still as far as I understand, as well as polyurethane end link bushings if you need or want those.
245 Turbo models use the same 16mm rear anti-sway bar as other 1981+ 245/265 DL/GL/GLE models and make up the difference in handling on 245GLT/Turbo models in the springs, shocks and the oe 15" Virgo wheels/tires. Only Sedan/Coupe models in Turbo/GLT/1980GT form use the 21mm rear bar.
With the stock 14" 185 tires there's no real gain to be had installing the IPD 25mm front bar and it will actually hurt wet weather/rough road articulation & overall grip and handling predictability in many cases.
Even with 15" tires, it's hard to see any notable gain from the IPD 25mm bar over the turbo 23mm front bar. The only time the IPD 25mm bar is really superior overall is with stickier summer 205/55 optional 16" wheels/tires (widest of the OE) in dry weather/fairly smooth pavement. It's unlikely many will drive on that ideal tire/road combination year round.
The rear IPD bar often hurts traction, but can be used as a brute force method to reduce rear grip and encourage the car to rotate if that is desired. Many times, it's better to install front bar only for more on-pavement grip on these cars and increase front grip over all for the intended use of the car rather than limit rear traction with a rear bar. Your mileage may vary.
