BMW M3 Dinan Underdrive Pulley E9x w/Steve Dinan

Dinan's Stage 1 Suspension System provides greater control over body roll by virtue of carefully calibrated spring rates designed to work in conjunction with the original-equipment standard or EDC shocks and struts. Dinan lowers the M3 by 1/2" front and rear for improved suspension geometry and an even more aggressive stance. Matching bump stops and replacement front guide supports are included that actually increase suspension travel by 0.6" for improved handling capabilities along with surprisingly civilized ride quality. The higher spring rates, increased suspension travel and improved suspension geometry give the M3 even more grip for faster and more predictable cornering capabilities. All of the EDC system features are maintained for cars equipped with the option.

Dinans high performance rear toe link adds precision and predictability when the BMW M3 is driven to the limit.

The stock rear toe link is built with rubber bushings and a curved foraged alloy rod which is designed to flex. During hard acceleration this flex allows the rear wheels to have excessive toe change under hard acceleration and braking. All of this flex in the stock toe link causes the M3 to be unstable.

Dinan stops the flex by replacing the rubber bushings with Teflon coated machined steel rod ends and the OEM curved bar with a straight billet aluminum rod, thus adding stability. The Dinan rear toe link also incorporates a hex nut shaped center to aid in the necessary fine adjustment of the toe link that is tough to achieve using the stock link. R280-0006
