Read through the very imformative guide on the VIII that answered many of my questions, but still have a few.

Couldn't find spring rates (f/r) anywhere, anybody know these?

I see the 8 gets inverted struts, anybody know piston diameter?

I also didn't see any alignment specs- curious on camber, toe, caster and what adjustments are possible, I'm sure toe is adjustable, how about front/rear camber?

I must say I am impressed w/ the setup described. Sounds like the chassis recieved major stiffening/additional welds. Lots of aluminum bits- control arms, lateral links, trailing links- even the rear cross member.

The sway diameters appear to understeer biased (larger front vs rear), curious if this is the case or not?

Also does Mitsubishi have a performance component like Honda- Mugen, Subaru- STi, etc?

Thanks in advance.

Thanks for the info. It's funny I did a pretty thorough search and oe spring rates seem to be pretty well guarded (or at least not widely published).

Strut piston diameter will likely be even harder to come by.

Good discussion on the Lime Rock thread!

I've been doing a lot of comparing lately and I like to do my homework .

My understanding is the 8 comes w/ a inverted strut, so there may be a good chance it's a monotube. We're fortunate as the STi v7 strut (that I replaced the oe strut w/- non inverted, dual tube, 22mm piston) is an inverted design, a pretty beefy 40mm piston and montube construction. There may be a good chance that the 8 may be similar.

I do like the multi link setup you get in the rear- I also like the fact that nearly every component is forged aluminum (even the cross member!). It sounds like that several of the links get pillow ball bushings- ofcourse they don't say which ones. Also like the fact that rear camber is adjustable- wish ours was.

I'm test driving one next week.

I'll keep poking around for spring rates.

Thanks for the help.

Hi,
According to Co-ordSport, the Evo VII stock spring rates are front 5.5 Kg/mm and rears are 5.0 Kg/mm. Don't know whether it's the same on the US car.
Cheers,

 

Search for my thread "evo stock alignment specs" or something like that. I have the factory spec camber, toe, and caster listed there.

Front camber is "adjustable" via an eccentric bolt. It can go in 1 of 2 ways to dial "-1" or "-2" front cmaber. In reality it seems to be less than this as my front end was like -0.6 on the "-1" setting, and most people report the most they can get from the front is about -1.7, like Claudius said. Rear camber is also adjustable but I don't know the limits. It's done via a bolt on one of the links. You can find pictures on mitsubi****echinfo.com, just look in the service manual "rear suspension" section.

 

Thanks for the info.

I did the math on the spring rates (I have to convert to English units unfortunately) and came up w/ 314 ft lbs front/ 285 rear- those seem high as the test drive I took I would have bet that the spring rates were slightly lower than my STi RA springs at 217/192. I could be wrong however.

Those are definitely "firm" rates for whatever country gets them. I'd like to run those rates in my rex at the track, but I'm afraid I'd be losing fillings driving around town.

Interesting you get "two" choices on camber. Is that site free- mitsubi****ech?

Thanks.

so, there rear camber is adjustable...? sweet...

 

how would this stock rates compare to these...?

960kg front - 870kg rear...?

 

would that be a simple conversion to lbs...?

which would be 435 / 394...?

 

Spring rates are usually expressed in kg/mm ie 5.5kgs/mm which equates to 341 lbs/inch, sometimes in N (newtons) also.

The specs you posted I don't have a clue on. If you converted them to lbs you have to multiply by ~ 2.2, not divide. Those don't appear to be anywhere correct unless the units are different.

i got those specs form the Eibach UK website for the EVO VII springs...
