Sure. But perhaps it's also the responsibility of a vendor to disclose known compatibility issues with commonly used parts? Perhaps even a safety issue? I imagine bad things would happen if the shock body let go as the front suspension was compressing for a 100 mph corner.

So you are saing that a RACE coilover was not designed to be used in conjunction with the same manufactures wheels, and ball joints that they sell and recommend....right.

At least disclose potential contact issues.

Not true

Also not true. Springs can contact axles, tires can contact the body, different size/offset wheels, different tires can cause different interference issues. Hell different camber settings can be the difference between wrecking a fender and not touching it.

A shock body that can't fit a 2.25" spring will be larger than one build to fit a 2.25" spring.

It has everything to do with shock body size.

:fael:

How is tire contacting the fender ok? If you dont care about your car, sure. But I do.

You can use the existing shock body with a wider spring perch and it will work fine. So larger spring does not mean bigger shock body. The öhlins we build at my work uses the same shock body OD as xidas, but uses a 2.5" spring.

Im not going to cut out my fender well.

Every single time a company came out with a new part that could affect suspension geometry, it is not the burden of the shock manufacturer to make sure their part complies. The company would never win. Exactly why I gave up on making a universal coil mount.

One thing I take away from fabricating and modding: If I did not personally verify fitment, it was my fault when it did not work, no matter how hard I try to place blame. In the end, I was the one who tightened the bolts and drove away.

If we were talking about a stock vehicle, then It would be a different story. If the NB arm hits the shock body with an alignment achieved with OEM adjustments, well then there is a problem.

If you care about going fast you take all the travel you can get. If your shock tower gets a light polishing so be it, run bigger bumpstops.

You missed my point. Any shock body that is built to fit a 2.25" spring would have the issue.

So the Ohlins you build at your work would also have this issue, its not a Xida issue.

Shock body size is not the issue. The contact is happening well into the bump stop. So if you would have limited travel by 1/2", this would not have been an issue.

What im getting from you guys is this, "Everybody who installs aftermarket suspension needs to disassemble the shock and do a stroke pass to verify no contact." Cmon, really...

.....yes, thats exactly what I'm saying.

If you limited travel by a half inch then the shocks would be worse for my car. I want that extra half inch of travel.

:facepalm:

You got a race car with race parts many of which alter all sorts of clearances/geometry. Surely at some point you can see how the burden of making sure it all plays well together would be on you, no?

I think we're all in agreement that 949 should have done everyone a favor and released a PSA about this when this was identified, but otherwise....

again, just a thought. I know I'd be really mad if I discovered this on my own car never even thinking it might be a possibility, so I totally understand the anger/frustration.

Are you not stuffing your tire into your fender?

Nope. I get a bit of a polish on my shock tower when I hit big bumps, but otherwise no fender contact.

In the rear I had some upper control arm to body contact, but the 5lb sledge fixed that real quick.

what are your camber settings?

I think im running 3.5*?

Car has been on jackstands since October though. Hoping to change that this weekend!

Aidan also has an NA, so clearances on a bunch of stuff are going to be different.

--Ian

It has been asked and its still not stated.... Spring rates on the xidas you have are 700/400?

Another reason why checking clearance is necessary

fix it pls. then come to laguna and watch your fenders get shafted as you go down the corkscrew :)

900/500

I've been down the corkscrew with xidas before. Also have run Hoosiers on my car at autox, and slammed bumpstops. So far fenders are untouched.
