Ive read about widetrack front ends and it seems interesting, I know robi uses them successfully.

I assume you just add a space to the front end? I was thinking about doing this on stock wheels with 245/40 or 245/45 tires.

Good idea/bad idea?

Any insight would help

Correct me if I am wrong but I was under the impression that with EVO's we were supposed to keep the tire width the same all the way around the car.....

 

tire size the same but you can widen the track

 

There would seem like there is only 2 ways to do this: Spacers or more aggressive offset wheels.

In your specific case, since you plan to run the stock wheels, you would need to use spacers (specifically H&R hubcentric spacers) to achieve a wider track. I too plan to run the stockers, and in debate about running spacers. Ive ran the H&R spacers numerous times, but not on a AWD platform.

Trying to figure out how big of a spacer is needed to achieve a wider track and the "Euro" look is near impossible as it seems noone is running spacers on stockers (that Ive found anyways).

 

Making the front track wider on Evo's helps the car rotate better in the rear and helps with turn in response when going into the curves......Most Japanese time attack cars run wider front fenders and wheels with lower offsets. Hope this helps.

You are correct, but you don't understand what Im saying. The only thing Im asking about is adding spacers to stock wheels


This is exactly what Im trying to figure out. Maybe you worded it better than me . I couldn't find anyone running the stock wheels with spacers.



Thanks for adding input chris but I already understand what you posted. What Im looking for in this thread is if anyone is running a widetrack front with the stock wheels and how large of a spacer they are running (also about fender rolling/rubbing.


Lets keep this thread goin

 

Here's a link to spacers.... http://www.livermoreperformance.com/...tml#mitsubishi
From my understanding, running spacers is not that good for the front end but I may be wrong.

 

what do you think, Having a small width of tires in the front and wider on rear have more conering performance advantage on autocross?

 

Assuming you used the same size from front to back, I cant imagine the drivetrain taking any more damage than just swapping the wheels out.

For example: I used to own a Jetta where I ran a set of H&R Trak spacers. In front, was a 10mm spacer, and a 20mm spacer in the rear. This flushed both the front and rear with the fenders (no rubbing ) and oddly enough flush with each other.

Being that the Evo is AWD, it would be wise to run the same size (just like tire size). I was a little skeptical that adding spacers could cause some additional load on the drivetrain, but I was reading about this Porsche GT2 recently, that was running a 25mm rear spacer (insane wheel combo ) with over 700whp.

Boltz - A few friends and myself are going to figure out what size we need to to push those stockers out to the fender. We plan to make spacers out of wood to determine what we need. Ill keep you informed.

 

Thanks, Id love to hear about it

 

I read in one of the magazines where the author spent time in Japan and they were making "midnight runs" against STI and the Evo had spacers or front rims with different offset to make the front track wider. If you look at a Mustang for example the front track is at least an inch wider to help it turn better. I realize the Mustang is a completely different car but the concept is similar.
Any time you widen the track you place more stress on suspension components.
Maybe the Whiteline roll center kit would provide similar results although I have read that its components have added stress due to their geometry as well.
One might think that adding quarter in ch spacers wouldn't place excessive load although I believe the wheel studs and or lug nuts might have to be considered as well.

 

Saw a silver evo on N/W side of Chicago Friday night with no fenders and the front wheels jacked way out. That wasn't you was it?

 

no that wasnt me.

a wider track in the front will def help the rear end rotate better. in aid to this, run a wheel that is wider in front (hypothetically 9.5") and a narrower wheel in the rear (hyp. 8.5") all on the same tire. this wheel created a rounded profile for the tire in the rear, causing it to rotate and break away more predicatably. the more vertical orientation of the front tire sidewall will keep it more stable. you can achieve that inital wider front track with spacers or an agressive wheel offset, but remember, moving the offset down (negatively) f's with teh cars scrub radius and all that other steering geometery stuff i'm still working through. def cop as many geometery correcting pieces as possible, all that white line roll center correcting pieces, and stiffer bushings. this kind of setup would be optimal on tight courses, but that easy rotation may increase quickly into a problem on high speed long sweeper type of courses, which may just mean you need to run wider tires all around, or change up alignment. lastly, dont forget if you realllllly wanna get that rotation, throw some toe on the front and rear alignment, IIRC its toe out in front, toe in at the rear, to get that point and shoot rotation.

 

Depending on the amount of camber you could easily run a 15mm spacer and I would think a 25mm spacer is usable with around -3.0 deg. I base this on looking at my own car on stockers (but lowered w/lots of camber).

You can always surf the net and look for cheap spacers to do test fitment with then order nice ones (hubcentric w/built in studs) when you find the correct fitment.

You could also put the car on stands and add washers to 3 of the front studs. Then run the wheel through its travel and see if it rubs. Do it until you find the optimum width then order something up from H&R or KICS.
