dbrunone Posted March 1, 2011 Share Posted March 1, 2011 So I read somewhere awhile ago (don't remember where) that my stock 07 Spec.B Bilstiens need to be rebuilt/replaced every 50k miles. That seems sort of excessive to me. I have 66k on the car now, and I haven't touched them. Is this actually true? Also, are the Bilstien HD's on TireRack an OEM replacement? Thanks for any help Link to comment Share on other sites More sharing options...
F-WDC Spec B Posted March 1, 2011 Share Posted March 1, 2011 If your shocks are fine dont touch em. I did alot of research on this and bilstien US Service sucks a whole lot of coconuts. a set of bilstien HDs and the cost of rebuilding are actually comparable. Im going HD soon. my shocks are done. I LOVE JERSEY ROADS! Link to comment Share on other sites More sharing options...

BAC5.2 Posted March 1, 2011 Share Posted March 1, 2011 No. They are different.

notthesnail Posted March 1, 2011 Share Posted March 1, 2011 The biggest benefit of rebuilding is getting the shocks matched to your springs. Give the spring rates to Bilstein (measured if possible, spec if not) and they'll rebuild your set much better than "close enough." There are 6 JDM versions of Bilsteins, one USDM, and HD, and they're all different. Link to comment Share on other sites More sharing options...
F-WDC Spec B Posted March 1, 2011 Share Posted March 1, 2011 HD are similar to JDM spec b. which is WAY better than ours for handeling. Im on my second set of rear shocks already. my front just went this winter. Link to comment Share on other sites More sharing options...
snow05gtRI Posted March 2, 2011 Share Posted March 2, 2011 hmm interesting. i've had HD's on my car for coming up on 2yrs / 40k miles... i'll keep this in mind. how can you tell when they're done? car gets floaty? I have them set up with STi Pink springs. Link to comment Share on other sites More sharing options...
notthesnail Posted March 8, 2011 Share Posted March 8, 2011 Large bumps will get your car floaty. Small bumps and sharp cracks will feel more harsh. In the front end you may start to hear clunking over bumps and the steering will follow ruts more (you'll feel like you're fighting to stay straight.)

sportwagon Posted March 16, 2011 Share Posted March 16, 2011 will they rebuild JDM struts? Link to comment Share on other sites More sharing options...
notthesnail Posted March 16, 2011 Share Posted March 16, 2011 I think the only difference between JDM and USDM or HD is valving, so there shouldn't be any reason they won't rebuild them. Link to comment Share on other sites More sharing options...
dr_sharp Posted March 16, 2011 Share Posted March 16, 2011 You should not have to rebuild struts every 50k. That's a streth even for coilovers. I pulled my oem bilsteins at 60k only because I broke 1 during install of springs. I replaced them with HDs because it was cheaper. lol Link to comment Share on other sites More sharing options...
BAC5.2 Posted March 16, 2011 Share Posted March 16, 2011 You should not have to rebuild struts every 50k. That's a streth even for coilovers. This. You should easily get 100k out of a set of struts. Bilstein doesn't make shitty parts, so you can expect them to last quite a while.

Draco-REX Posted March 16, 2011 Share Posted March 16, 2011 Just to be sure, do the USDM spec.B Bilsteins and the HD Bilsteins have the same spring perch height? Or are the HDs more like the LGT struts? Link to comment Share on other sites More sharing options...
dr_sharp Posted March 16, 2011 Share Posted March 16, 2011 Exact same fitment between the two. Only difference is HDs are valved slightly more agressive. It's a bolt on for you. Also, the HDs have a map of the Nurbergring printed right on them! lol Link to comment Share on other sites More sharing options...

Plus a new rod, Plus new bushings, plus shop labor, plus dino evaluation, plus unwanted rush service (heard from other forums) NOTE: All revalved shocks and struts are dynamometer performance checked. Additional parts and services that are not included in the normal scope of revalving will incur an additional charge (examples include shock rods, tubes and/or end loops and machine work). Development fees apply if it is necessary to meet specific valving targets. Dyno sheets are available upon written request. Replace piston rod (Appropriate rebuild fee from above must be added) Link to comment Share on other sites More sharing options...

motorbykemike Posted March 18, 2011 Share Posted March 18, 2011 What? Do you know what a dynomometer is? the damper, strut , shock , piece of rubber , whatever it is is measured on a machine that records the action or resistance to movement . it happanes from slow speed to high , takes about a minute to do & you press print & get a paper w/ a graph on it , then you check spring/wheel rate vs carried load & determine which way to go w/ valving .

motorbykemike Posted March 18, 2011 Share Posted March 18, 2011 my hd's did not have the cool "ring" map sticker , but i did have them revalved , 320.00 inc shp both ways for all 4 , i did only send the damper part of the fronts instead of entire assy , alot less weight , smaller pkg.

dr_sharp Posted March 18, 2011 Share Posted March 18, 2011 that is a chassis dyno A dynomometer measures torque from a rotating machine whether its an electric motor, an engine, or from the wheels of a car. It is not a tool that can measure resistance of dampers in any of its forms. lol Link to comment Share on other sites More sharing options...
