if so how much?

or not then i'm okay?

I've installed nf210's on my D but it seems like the back end has settled nicely but the front seems to sit higher then the back. Springs been on for about a month now.
Will get pics up later.

no one's got a yes or no answer?

Try Yaris world - also note that FACTCAT Motorsports offers bumpstops for Yaris suspensions and advises against cutting.

didnt cut mine - no problems

Tanabe springs usually sti lower in the back. At least that the way it is with the DF's not sure the NF's.

Stance has notting to do with the bump stops.

A shortened spring puts more stress on the shock - called "riding".

It's important to know if the shortened stop is needed. Most DF210 installs talk about trimming the stop (which has drawbacks). I also want to know the answer to this question. If you get it wrong, the damage isn't immediately realized.

Does anyone know of a more technical scion forum?

Thanks.

if you don't shorten the bump stop, you could damage your upper strut mount under hard/heavy compression. not a big deal with y'all's one-bolt front setup, but on a 3bolt upper, it can really make life difficult and a dangerous ride over bumpy terrain. (i've seen the front of a car come airborne on the freeway simply because the bump stops were not lowered, and the driver hit a dip that just bounced the front off the ground). rule of thumb.. if you drop the car 1.5inches, cut off 1.5 inches of bumpstop.

the car really isnt that old, and not a lot of people or companies have really torn that deep into the car. if youd like to tear deeper into yours, make sure you post the info so that way this one is technical enough for you and everyone else.

i have not cut my bump stops, and have not had any problems on even the roughest of roads here in washington. cutting them is not going to change the ride height either.

the TRD springs typcially lower the car 1-1.5 inches. the NF210s lower 1.4 inches in the front. there is nothing in toyotas TRD lowering spring installation instructions about cutting the front bump stops:

the NF210s are a similar drop to the TRD springs in the front, so cutting the bump stops should not be necessary.

I hear you, but you may be putting double miles on your shocks by putting too much initial load on them. The issue is that you must properly balance the load between the stock and the spring.

the shock doesnt carry any of the load, its a damper. its meant to reduce movement.

and all of this still has nothing to do with the bump stops, all the bump stop does, to put it bluntly, is control when your suspension is going to 'max out' and begin to transfer the energy from the bump directly into the chassis.

yes and it does this by slamming into the top of the strut housing and the top mount

yup yup, and thats when bad things start to happen. but im pretty sure if i hit a bump big enough to bottom out the nf210s, there are going to be more problems than with just the bump stops. even though the springs are shorter than stock, they also have a higher spring rate, so it is going to take slightly more force to get them to compress as far.

Hey guys... The Scionmag.com RS 1.0 xD is getting fitted with FCM test bump stops Monday. Once Shake has done some testing I will report back... Hope to also have information at some point on pricing.
