Just a tid bit to confirm how awesome the Ohlins are... While out cruising around with a frined yesterday (he has an Evo X on stance supersport coilovers), he could literally see how much better my car worked in bumpy corners vs his car by just following me, and watching the tires follow the road imperfections, all while bouncing all over the place in his car and fighting it to maintain a line...lol

 

I gave in and placed my order last Wednesday, should have them by the end of March to replace my 7+ year old chinesium coilovers.

 

Whoops!

 

Nice man. Definitely won't regret it.

Thanks for spamming the thread...

 

I'll have to make another thread about this, but I pulled off my old DFV's and found one of the rears has a bent shaft. Does PSI have replacement shafts if they do rebuilds? I'm not sure I want to have to pay to rebuild these just to turn around and sell them but certainly cant sell it the way it is.

 

I'm fairly certain PSI has parts for them. I know when I talked with them on the phone the sales rep told me they were capable of fully servicing/rebuilding the dampers in the future as well, they aren't limited to just revalves. So I would assume they can get all the parts.


On another note, how did you bend a shaft???

 

I've bent two fronts which is why I switched to AST's inverted design....but never a rear lol.

 

The Ohlins R/T's are an inverted cartridge in the front. I've seen the standard front struts bend shafts on other cars. I think the OEM dampers on our cars are inverted in the front, they have a large shaft.

 

The original R/Ts were fixed body length, but were they also not inverted? I could see that being a big issue for shafts bending. I have no clue how you bend a rear other than spring force causing a load when large angle from heavy lowering.

I think I'll look into making a coaxial spring perch for the rears after seeing this. Should be an easy thing to design and machine and would be much nicer keeping the spring square.

 

did that not show up in the alignment? or am I picturing this wrong?

 

I doubt it was spring/downforce, more likely curbing

 

On the rear, the shock has zero effect on alignment.

 

Rears are double wishbone/multi-link type and side load on those is minimal if any.

Either full extension did something wrong (unlikely though) or most likely they just bottomed out.

 

Yeah guys, this is rear shaft that's bend. Their is no coaxial alignment on the spring and I think the shaft size is probably spec'd for rates closer to the original range. But I'll model something up real quick today and try to prototype a solution in the $100 range for anyone else that might get worried about the same thing.

I think the contributors is increased spring rate (mine is 800lbs) and how low you are or hitting big bumps. Right height will increase the angle on the spring which is just putting a bending load on that shaft.

 

i doubt the higher spring rates bent the rear shaft, there must be something else going on. i know cars that run much higher spring rates on coilovers and never heard of springs bending shock shaft.

on the inverted strut, the top "shaft" is actually the shock body, and the shaft in inside at the bottom. hence inverted shock.
