Get the tape measure out! EVO I-III & GSR Wheel Track discussion

4GTuner

Help Support 4GTuner:

Figured out where the extra wheel track came from :unsure:. The lower control arms on the EVO I wreck I bought years ago has what looks to be bent lower control arms that increases camber dramatically! This may be contributed to the handling of wrecks on and off forklights, cranes etc. Coincidentally, both left and right lower control arms I took off my car are identical in measurement and angle and I couldnt see any heavy impact signs on the arms from underneath that would have been a tell-tale sign. It was only when compared to another set of arms this morning that I realised the difference :thumbsup:

Anyhow, when I replaced both arms today the wheel track dropped back a considerable 60mm to 1440mm (it was 1500mm before with the bent arms in place) and now the wheels have a decent toe in thats got to be sorted tomorrow with a wheel alignment. This is a good sign that everything's back on track for stock wheel track! :lol: Stock EVO I front track is 1450mm, so with my 40 offset mags and slight camber my front track should end up being 1460-1470mm... perfect!

Now I'm happy that there's a logical explanation for it :w00t:

lol thanks man... admit it, you just want a nibble on my pecks too dont you? lol

Its wierd how it was not picked up on even at the place that did the wheel alignments as they originally adjusted it all to suit and the car drove fine with the bent ones in place. Both left and right lower arms were the same angle so it went un-noticed throughout the whole conversion until I was questioning the extra wheel track after the original alignment.

I measured another pair of stock EVO 1 arms against them and walah, the extra track and scope for negative camber wasnt from the coil over camber bolts at all. In fact the guy at the wheel aligners said he cant get fuk all negative camber with the normal arms in place now and said the bent ones were heaps better for camber and handling

He suggested I get some adjustable camber tops now and it took me half a second to agree with him

Sent latest info to engineer and there's just 2 question marks at the moment to finalise now.

Now that the weight of the car has been established at 1240kg, the current 84 (500kg) load rating of the 205/40/17 tyres may be too low. Considering GSR's are 1190kg stock with a load rating of 85, and EVO's are 1245kg with load rating of minimum 87.... my 84 appears to be too low. However there's comparisons to be made as there is a general consensus that an an increase in tyre width and a decrease in tyre profile (both) can result in a lower load rating which can be used.

Last of all is my projector headlights. There's no "E" marking on them. But there's no "E" marking on the Mazda 3 projector headlights either so there is a question raised about projector standards.

Normal halogen headlights scatter their beam in many directions and thats why most glass lenses you see on normal headlights have cast lines in them so as not to interfere with oncoming traffic. Projectors use a lens that concentrates the beam more precisely and therefore why the headlight lenses on projectors dont require casting lines in them. I'm not sure of the European standard for them, nor the Aussie standard which is based on the Euro standard... there doesnt seem to be a clearly defined ruling on them that I could find. Sort of like with new LED headlights where the Standards arent written quick enough to keep up with technology.

The ball is back in the Engineer's court for these last 2 items. If I need to buy new tyres so be it. If I need to put stock headlights back in then that's what I'll have to do.
 
Theres quite a few new casrs out there without the "E" on the headlights... i noticed a new Lexus today never had 1 either
 
dont go out and buy new tyres!!!!!! just borrow some till you get passed, jeez... i have 2 sets here you can borrow, 1 set of 4 on 16's and a set of 4 on 17's the 17's have all new tread, i will check out the load rating for you.
 
hey rob,did you measure bolt hole to bolt hole on your crossmember by any chance? im after that measurement to check a crossmember?
 
Na George I didnt sorry. I know the k-frame came from an EVO 1 so no point checking the k-frame length. It's the same for any GSR or stock CC Lancer. I suppose you can measure your EVO II K-frame to determine it's length too. There's been debate over whether the shorter wheel track in a EVO 1 up front (1450mm) compared to EVO 2/3 (1465mm) is the width of the K-frame, or whether its in the lower control arms? According to CAPS the EVO I-III has the same part number for the K-frame... although the pics look a little different.

If they are the same K-frame, then you would have to say the lower control arms make the difference. Some people have measured them and said they are the same length... possibly true.... but perhaps they have a slightly different angle in them which makes for the extra track? (as in my circumstance at the top of this page)

The only true way of determining what's correct (instead of saying 'I heard etc') is to physically measure wheel track with stock wheels on with both different lower control arms fitted to the same K-frame.

See pics from CAPS below showing same item numbers for both K-frames, but different part numbers. (The same goes for the lower control arms).

Oh, I have a normal CD5A/CD9A K-frame sitting in the back yard and I will measure the centre of bolt hole to centre of bolt hole for you tomorrow. If you get a chance to, measure the one you have and we'll compare the difference.
 
thanks heaps rob, I dont have access to my car atm and that would be a massive help mate. cheers.

ill double check my mates measurement but 750mm rings a bell for some reason, but Ill confirm.
 
The FWD K-frame and the GSR/EVO1 AWD K-frame have exactly the same wheel track and use the same lower control arms Mick. The bolt holes will be in the exact same spot. you can measure the one at Frankie's place if you want but I bet you they're the same length :p
 
Okey dokey

* 930mm from centre of K-frame bolt holes (centre of bolt hole to centre of bolt hole) for the long bolts that connect the K-frame to the chassis rails.
* 750mm from centre of bolt hole to centre of bolt hole between both lower control arms.

See pic - now its your turn George :)

cheers rob, yep thats what we came up with, 750mm on the front holes. which means as suspected his crossmember is an evo 1 one......bugger

i was checking for my mates gravel project and just wanted to make sure he was fitting a 2/3 crossmember which it appears he isnt!..bugger.

nicely done :) George, when you get a chance to, it would be good to know the measurement of your EVO II k-frame too... just to see the difference.
 
i measured and fitted a e2 kframe into the gsr last night, it measured 930mm and 750mm. do you know the measurements on the gsr ones? the look longer then 750, perhaps shorter lower control arms.

If so, can you run a gsr kframe with evo 2/3 control arms without problems?

Interesting... if thats the case then the extra track up front in E2/3 is indeed from the control arms and not the K frame.

I'm running the Evo 2/3 control arms in my Evo 1 (same as GSR K frame) without any dramas. Only things you need are struts with the mounting tabs for the swaybar links, a swaybar, the links, Evo 2/3 swaybar bracket and bushes, and plenty of patience.
