GC8 WRX Upgrades - LSD and Whiteline Suspension Bits - Project Budget Track Hack WRX Pt8

With a Top-10 finish under our belt in the Rallysprint series, we wanted to go faster. Rather than increase power like most would, we attacked a couple more areas we knew improvements could be made. WRXs have open centre diffs all round so an LSD was needed and the suspension could be tweaked further so we spoke to our friends at Whiteline.

[@ricepony33]

Thanks for this series, really shows how if you focus on the essentials and not the power you can have an awesome and reliable little rippper!

i did my SF5 forester 1 at a time cause i am a pensioner -and did braces sway shocks springs white line front and rear with the bump steer . great = like a go cart - on rails = 2 way LSD pushes all the time - sleeper looks like mum`s car ej207ra sti spec C jdm .

Looks like you could use better lights for the night runs. A curved light bar above the windscreen works really well. The trick is to mount it far enough back so that it doesn't reflect off the bonnet. Using small mounts and water proof quick disconnects would render the car still cool looking for day time events.

[@bigkaswrx8115]

This really speaks to the chassis engineering and all round great performance of the GC8's - Ive owned 3 of them and Im absolutley addicted to the drive of those cars

[@aaronwilkie6574]

keep up the good work love the old gc8s , sounds sexy too.

[@azza9575]

The secret to the 5 speed is using the stock clutch and that will handle 250kw

[@92soldier]

100% can vouch for this

[@GingerNingerGames]

How does that work? What difference does the stock clutch make? Does it just slip so the gearbox can't break?

[@gabemiller9873]

ya thats what I have done... only down side is highway pulls in 4th and 5th slip

[@Kaffarov97]

@@GingerNingerGames Essentially yes. A more grippy clutch can break the weak gears in a 5MT.

I absolutely love the car and the way you are building it, keep it up. This car helps me keep my hopes up for doing something similar with my usdm gc wagons. Yes, I said WAGONS. 😂

[@joeldavis3152]

Front diff next, you will love it.

[@MotiveVideo]

Joel Davis j on bigger tracks it’s great but on a tight track like this is would make life a pain and isn’t needed on our power

[@joeldavis3152]

@@MotiveVideo I have one in my wrx, I use it for skidpan and gravel racing, car makes about 200kw atw. The rear diff will be good on its own at first but eventually the center diff will start to fail and it wont feel as good. Plated rear with open front puts a lot of strain on the center diff. Just my experience.

[@omer9572]

@@joeldavis3152 so in gc8 wrx should i upgrade the center diff too?

[@joeldavis3152]

@@omer9572 You can leave the centre if you have plated front and rear diffs. It's the imbalance of one good diff in the rear and an open front that puts strain on the centre diff.

[@omer9572]

@@joeldavis3152 i saw cusco testing and showing their lsds on gc8 and the rear+center made huge difference the car rotated on the gas pedal like a ballerina dancer , but i should look into front diff too

Love your work Andrew keep up the great work.

[@princepietrom]

Great job

[@PerformaIT]

Please add a torque biasing diff in the front and let us know what improvements that makes please! Great videos - love the content! :-)

[@PerformaIT]

Oh and stiffen up the centre diff fluid too. Make alignment changes to dial out the understeer.

[@headcheese69]

My vote is still for a short ratio steering rack. Having the quick rack is a night and day difference.

[@alexlai4566]

Awesome video! Would like to see a budget car beat a GT3!!

[@tgracing5532]

Never 😁

[@dougalsmith7795]

Pleased to hear you had the alignment from Road & Race performance. Peter corner balanced and aligned mine a few years ago and does good work. Keen to see your times coming down even more.

[@MattBerrymotorsport]

Looks like great fun! That turbo is punchy!!

[@stevesteven7650]

i love watching this , love the work you do keep it up, i wish i could do that to. i keep looking out for a wrx lol

[@AdrianRec]

Good moves little changes to get maximum seat time & better times... Once you go too far you will not enjoy it as much as you are currently... Trust me.

[@Kaffarov97]

My favorite series, keep it up!

[@skatetown100]

I'm late to the party.. but my GC8 is gonna get all of this !! whaat whaaat

[@dolphincatcher2491]

I know you said reliability with stock car is key but with your connections I’m sure a small Garrett turbo upgrade and a bigger cooler just to give a little extra punch and keep those IAT temps down should be a future upgrade

[@michaelgunning347]

Should have said what power it is currently at , Std ecu or what , but ya a nice modern quick spool turbo , just a few bit would make such a difference too

[@Sf_Mason]

Two questions or suggestions. 1: What's up with the rev counter? is it disconnected? or blown fuse? would be nice to see what the engine revs are on the footage. 2: REgards to the shifter position, what's the thoughts of getting a short shift kit that brings the shifter up to beside the steering wheel, this would give you better ergonomics and reduce time of one hand on wheel. Just a suggestion.

[@danspeed7039]

What was the wheel alignment specs?

[@CUSTARDP00DLETK]

Should replace the gearbox with the sti 6sp.

[@PBMototsports]

For what he's doing with the car there would be way too much shifting involved. If he decides he need more power and a stronger trans his best bet is to upgrade the 5mt with straight cut gears and stuff like that.

[@Jeffball610]

What's the deal with your tachometer? I'm too afraid to drive without one at the limit. But you know your car and what the motor sounds like at what speed, so it works for you. An LSD made a huge difference in my overpowered Datsun 510, but I'm curious why you went aftermarket. I'm not the most knowledgeable about Subarus, but I would guess the STi would have parts you could more cheaply install and work just as well. New parts are more desirable obviously and you know their history (or lack thereof), but I would just guess there would be more STi stuff on this car. My opinion is biased due to the fact that nearly my whole car is made of parts from other cars.

[@MotiveVideo]

Jeffrey Ball the car is slow enough that no tachometer bother me and know the car really well. Factory diffs aren’t tight enough and wear out and we have 4.4 ratio. Went with what we knew and bought a mechanical centre

[@gpajic1987]

I'm about to put a rear LSD in my GR Yaris, would you recommend rear only or will it induce some understeer? Cheers

[@MotiveVideo]

Do rear first in our opinion. It will reduce understeer

[@miguelsanchez6465]

im so sad my dad junked his rs 2.5, tear... hey andrew please fix the tacho

[@taylorasbury4980]

Do the STIs of this generation use all open diffs as well?

[@connorconway2021]

Hi, I have a version 5 STi and it’s a mechanical LSD in the rear and a viscous centre. RAs and Type r of the era also have a front LSD.
