Default 2002 WRX sedan vs 2006 WRX wagon handling

I just drove a 2002 WRX sedan for the first time. I've never driven any WRX besides my 2006 WRX wagon. Now I'm bugged: my friends sedan feels about the same handling wise as my wagon, and he has NO suspension mods! We both have 17 wheels with the same exact tire.

Granted, it was a short romp on the street, but I felt the body roll, rate of weight transfer, and chassis stiffness seemed similar. Next week I'll get to drive his car more to really see, but the initial impression really bugs me.

Besides the weight difference and the slightly wider front track, I was under the impression that there is basically no difference between sedan and wagon. (ie springs are basically the same)

He probably had a 20mm rear swaybar, which makes a gigantic difference over the later years 17mm, especially in steering response and 'turnability'. That made a huge difference in feel in my car.

only major part differences i can think of is that 20mm rsb vs 17mm rsb

metal front endlinks vs plastic front endlinks

06 wagon has sti type lateral links?.... or was it something else...

and about 100 in weight...

I've always found the sedan to be a markedly better handling car out of the box compared to the wagon. The 02 sedan was a bit more rotation friendly (with the 20mm rear sway) compared to later iterations but the 04+ dampers were definitely better than the 02/3's.

This is so making me want to swap to sedan arms.

I definitely noticed a difference when swapping to sedan arms. Plus, you get the free extra neg camber if you run wagon struts.

Yup. I'm thinking that since I'm currently limiting myself to 225/45/17 tires, I'll be ok with sedan arms (sedan half shafts necessary?). And if I ever go to the STi wagon pinks on Tokico Dspec's I won't pay the camber penalty.

Hmmmm... tempting.

so far, with probably 20k miles, no issues using the wagon half shafts. It then gives you proper fitment with larger whiteline front swaybars. I went with Whitelines 24mm adjustable. Feels great.

I definately noticed handling difference between stock sedan vs. stock wagon, wider track and lower CG on sedan.

Hmmm, some interesting specs for MY '06

Track F/R (inches)
------------------
58.5/58.3 WRX sedan
57.7/57.3 WRX wagon
58.7/58.9 STI

I didn't realize the wagon had almost 1" narrower front AND rear. What is the rear differential from? Ride height difference?

Rear lateral links are longer on the sedan compared to the wagon, half shafts too. Been that way from the bug-eye period onwards. Possibly due to tax reasons in japan. Supposedly wider tracks are taxed at a higher bracket, so subaru left the utility wagon with the old track and cheaper tax brackets and reserved the wider track for the performance model sedan.

so are the struts and shafts different in the rear for the wagon too?

Could any of this have to do with ride height? IE, the lower a car goes the wider the track; until the arms go horizontal then things start going in again.

Huh, very interesting. I had no idea... I thought only the front suspensions were different between the two. Thanks for the info. Interesting note about the half-shafts too. Are the SPT lateral links then applicable to both the sedan and wagon, or for sedan only?

I always thought the struts were the same, but now I'm curious. I had the same thought about ride height, but that 1" track differential seemed too big to be due to ride height.

ride heights are the same wagon sedan (the fronts are shown higher for the wagon, but it's simply the fender flares are higher by 10mm)

struts are different both front and rear, BUT the sedan struts in the rear don't appear to penalize in camber loss like the sedan fronts on a wagon

lateral links are different lengths sedan vs wagon (10mm/side)- canNOT use sedan lateral links on a wagon (well you can but your axle is likely to pop out )

I wonder if this sedan/wagon difference has carried over to the 08 hatch and USDM sedan

My undserstanding they are on the exact same platform so track width should be the same- there may be minor differences in spring rates/damping

Let's say one was interested in going the route of putting sedan arms and links in the rear... what is the list of things that is necessary? FRONT seems to be covered, but the REAR isn't.

Also, I want to understand what is gained from doing the front and rear...

Is a wider rear track going to increase rear traction and reduce roll, but decrease rotation?

Is a wider front track going to increase front traction and reduce roll, and reduce understeer?

etc

rear requires sedan lateral liks and sedan axles

wider front track wil dial out some understeer, probably more importantly it will give you more neg camber (assuming you stick w/ wagon struts)

unless you need additional clearance in the rear for bigger wheels/tires, I think just doing the front makes more sense
