Oh yeah, MVP is located in Portland, Oregon. their phone number is 1-503-892-9405. Someone that lives near them should go over there and see whats up. Find out who machined these for them and whether we can get them made again (a Supra specific version maybe). I'd do it but I'm on the other side of the country and I know there a lot of PacNW peeps on here.

have you actually taken measurements to see if they fit?
this is the exact thing i am trying to do, but our setup is a little differnt.

first, we have much larger diameter springs, so getting smaller diameter
coilover springs may not sit on the control arm unless some kind of lower
perch is welded in place

second, our bump stop comes very far down on to top mounting point of the spring, and it would look like a very short spring would be needed if any drop is desired.

still the easiest and safest method to try. i am going to try some stuff on
my parts car with a prelude kit.

Making an adjustable perch for the std springs is interesting and certainly has advantages over the coilover shock, but the size of the collar and thread needed makes it difficult/expensive due to the spring ID.

I'd be happier probably reinforcing the upper shock mount, making a decent 3 point strut bar and doing it that way, but it my have to wait till after the car is engineered. I'll probably do the fronts then as well. The main reason for doing it this way is the shocks already have the platforms on them :lol:

Any feedback from the Celica GTS conversion with the issue of the body structure ? Anyone ?

Instead of getting these rear height adjusters made specifically for our application why not get an existing adjuster with a spring that coils down to a smaller size like this.

Or get a perch like this and look for a spring to match.

Look under the coil over section, bottom of the page.

This is just a thought, I just want some advice and to press on with our progress in having some chamber adjustments so I can stop eating tires.

Well the MVP adjustable perch is for a full size spring the same size (or nearly) as ours. So it's already been engineered and built. They made versions for 200s and 7/900s, I had measured these awhile back but don't know the measurements offhand. I do remember they were /should be compatible with our spring diameter. I'd like to have rear height adjustment but otherwise I'd go for some kind of spacer to restore ride height.

If that is the case, it will be pretty easy to make up a small collar to make up the difference.

Can anyone contact MVP from that side over there ?

I'd be keen to hear a price/availability/details for sure

well, what springs would we use with this larger
diameter lower collar?
i wanted to do this for cheap, but it looks like a
$180 dollar order of whatever spring rate we
want will get the job done.

i guess we can put that lower collar on the
stock or eibach or st springs, that would
not allow for further lowering of the car.

i want to be able to go from just above stock, to quite a bit lower
lower for autocross, higher for drag racing and street

Well the beauty of it is you just use whatever springs you have now Just any stock or aftermarket spring. If you want to go lower then just cut the spring down a coil, this would increase the springrate as well and allow you to raise the car back up. I must say though with the ST springs I definitely wouldn't want to go any lower, I actually want to raise the rear a hair.

but it looks like a

So is that what these collars cost for a pair ? USD $180 ? Does that include the springs, or is it just a pair of threaded collars plus the locking rings ?

Material is ?

[ksourounis]

from the tunermotorsports site, it looks like its just the adjusting sleeve
in which case we would need another 100 or so for springs

 

[bbaacchhyy]

What is the web address/link so that I can have a perve please ?

re:

I hate to bring another old thread back from the dead, but I've been thinking about these rear height adjusters lately, and was wondering if anybody here has actually done it (ksourounis or white_mk_2)?
