TOUR­ING CARS/GT3

Motor Sport News - - Ohlins Dampers -

Ohlins has a near-mo­nop­oly in the World Tour­ing Car Cham­pi­onship, sup­ply­ing every make of car save for the Honda Civics. It’s a sim­i­lar story in GT3. In a typ­i­cal Blanc­pain GT field, at least 60 per cent of the cars will be run­ning Ohlins kit, in­clud­ing mar­ques such as Audi, Bent­ley, Mclaren and Lam­borgh­ini.

“The loads are sim­i­lar in GT3 and tour­ing cars,” says Jarl­mark Nafver. “For a GT car, the damper has to be slightly more durable as the peak load­ing can be slightly higher, es­pe­cially when they go to tracks like the Nur­bur­gring and tend to go off the track more of­ten!

“A GT3 damper will gen­er­ally be big­ger than LMP dampers whereas for tour­ing cars it will be Macpherson struts, at least on the front. The TTX work­ing prin­ci­ple will be the same for all and the key to per­fo­mance.”

Durability is crit­i­cal here, but as­ton­ish­ingly even with the af­ter­mar­ket prod­ucts, Ohlins dampers can achieve re­mark­able longevity. Given Ohlins has lit­tle di­rect in­volve­ment with GT cus­tomer teams, only do­ing de­vel­op­ment work with the man­u­fac­tur­ers, this is vi­tal.

“With the af­ter-mar­ket prod­ucts, we try to make them as reli­able as pos­si­ble,” says Jarl­mark Nafver. “Of­ten, they get to a GT team that doesn’t take care of the dampers as well as they should. But the last durability test we did with the damper sys­tem with­stood six con­sec­u­tive Nur­bur­gring 24 Hours with­out ser­vice. I wouldn’t rec­om­mend go­ing that far, but if they get ser­viced every 60 race hours then they will be happy.”
