I did notice that the bumpstops supplied were much softer than what i was using on my old Bilstein setup, but didn't really stop to think what that meant at the time, because i wasn't really focusing on that car.

Have you talked to your pro suspension builder?

Bump stops come in different hardnesses and heights. Ride heights are adjustable too. So are springs and damping. You are buying an aftermarket off-road, race product. It will require you to tailor it to your particular needs. It probably works just fine on many cars the way it is.

The rubbing is a bad thing, but complaining about the bump stops is like plugging in a megasquirt and expecting it to be perfect with the base map.

You were more focused on much bigger things like what happens when you lean hard on one side and then let go.

Bump stops are independent of ride height. It's reasonable to expect that stops provided for a coilover system that is tailored for a specific chassis within a normal range of spring rates would do what they're supposed to do.

The amount of rubbing here may not be a bad thing and may be working as intended, but George is not outside the realm that the supplied bumpstops would still be expected to work properly. No work/tailoring should be necessary.

^ that. You cannot adjust shock body height with xidas. So they should have hit the bump stop way earlier/had a stiffer bump stop. There is only preload adjustment, so if you are in the area of a race/performance ride height, you will be in the bump stops a lot. There is nothing I can do except go up in spring rate to keep me off the bump stops. They just should have been made so that the "hard limit" (max compression) is just before tire contact. Simple as that.

Nope. We have found it faster to run the shocks the way we ship them. Our competition record stands for itself. You are however, welcome to experiment with taller or higher durometer bump stops.
Making a car faster is always a process of experimentation. We did that, engineered Xida Race from scratch. Nothing in that assembly is an oversight or accident.

You need stiffer springs. I'd suggest 1100/500.

I would like to see data backing that up. I find it hard to believe that stuffing a tire in a fender is faster than not doing so.

bad joke~~~~

If you have a stiffer spring like he's mentioning, your tire doesn't bump into fender.

but it shouldnt have the ability to do that. thats the thing. whats the point? its useless wheel travel that is only causing damage.

WHAT??11!!oneoneone

hold the phonesso they limit it and the next guy complains about the limited travel cause his car is higher and his tires are smaller? I dunno

That would not be the case. A higher ride height would give you more bump travel. You would still bottom the shock in the same exact place. if you were running a 205/50/15 you would hit the fender even sooner. im running a 40 sidewall.

Your 40 sidewall is only 0.3" diameter smaller than a 205/50r15. So 0.15" earlier. Which is a negligible difference.

either way, you would still bottom the shock in the same place.

You have the race version and not the longer body street version?

Every car is slightly different. A big of tire polishing your shock tower isn't bad. You are working with the tolerances of a "race car", not a street car.

You should always test the full travel of your wheel without bumpstops when making suspension changes.

There are a variety of factors that affect clearances when setting up a shock. Camber, ride height, ELBJ, which control arms, age of bushings. When working with something at the limit then you can't always build a "plug and play" product.

A xida is not much different in this area than any other shock body designed for a 2.25" spring. Any ohlin would do it, a Feal or a Fox might be worse due to 2.5" springs.

In the end it is up to the car builder to make sure that everything clears and functions correctly, not the vendor of a shock.

What are your pinch weld heights set to, MiataMan00?

Don't you dare bring personal responsibility into this! How dare you!

He's running non-stock wheels and non stock tire size on a non stock suspension alignment, using full custom lower ball joints, and is complaining that his non-stock parts don't all fit together without touching anything like stock.

Yeah, it's Emilio's fault. :rolleyes: Hahaha!

yes, race version

If the tire is rubbing n the shock tower that IS bad. Race car, street car, it doesnt matter.

There is no documentation saying that there might be an issue with contact between the shock body and other parts. Expecting hundreds or thousands of customers to do a stoke pass is not reasonable.

Spring size has nothing to do with this

Exept when the vendor is tailoring the shock to work with your specific chassis, and gives you no shock body height adjustment. That just puts the customer in between a rock and a hard place.
