wrx chassis vs sti chassis
wanted to know if the chassis is the same. or did they do chassis improvements to the sti one. ie better welds more sub frame reineforcement welds. or is it the same.

Good question. I used to think that the only mods were bolt-on suspension pieces, lightweight back window glass, etc., but Ralliart modifies the production Lancer with additional gussets and welds to the factory tack welds on the chassis before it can be called an Evo(lution). I wonder if the STi has some full-length welds or gusseting to stiffen the chassis. It would serve to further reduce chassis flex and make the suspension and steering work even better. Prodrive does extensive mods to their WRC cars even before the roll cage is put in.

I think your best bet is to write an e-mail to soa and see if you can get an answer out of them. This is a great question, if you get answers please share them.
For a small incling of the differences search for the improvements between the 04-05 STi, just to give you an idea.

got reponse from SOA
Hello Mr. Apalis:
I apologize for the delay in getting back to you and appreciate your
patience. I have been advised by our Technical Services Department that the
chassis and the frame for all of the 2005 Impreza models, including the WRX
and WRX STi models, are the same.
Thank you for the opportunity to be of assistance. If you need any future
assistance, please feel free to contact us again.
Best wishes,
John J. Mergen

looks like the chassis is the same. so you can buy all the sti parts to make your wrx a STI.

from what i understand the sti is about 200lbs worth stiffer because that is the amount of extra metal it has over a wrx and yes i know it isnt 200lbs heavier because the few light weight parts it has but yes it is much much stiffer
if i cant find the link but there a crash involving a sti in canada back in early 04 and it hit a jeep at 100+ mph and shot the jeeps axle a hundred feet and sending the rest of the jeep spining into a parked civic prety hard and you would think the sti would have looked like a little ball and the person driving would have gone to the hospital but the car had the front messed up good and a little of the door but the frame looked straight and the kid driving was arrested

i remember reading about the added metal to the frame that is welded to it and 200lbs worth of suspension extra i dont think the suspension upgrade added much weight because a inverted strut compared to a noninverted strut weights about the same i know because i weighted my V5 vs my L strut and the inverted was only 4lbs heavier
and take into account the the sti has alot of lw components already and is still that much heavier than a WRX
