My front is neautral no toe yet. but i might go a small toe out before next week, 1degree would be approx 4mm i think so a bit less than that.

early next year i have to upgrade the turbo to something still focused on no lag and good power delivery so maybe 18g billet suit my rev range and requirements or even 16g. who does these as whole units ready to ship?

Neutral toe should still be grippy at the front

The problem with neutral is as the suspension works youll go into positive and negative toe angles so you're best just going toe out. Gets back to the anti lift kit being the game changer for you I think

The more aggressive you go with toe the more scrub straight line speed, so I'm going same set up with half the toe front and rear next I think

Mines running 380bhp on an SC36 turbo, I want something hybrid and ball bearing as I find mine laggy

DCT gearbox and about 460bhp make it a weapon weapon!

He's on coilovers and good tyres also

Got to be the anti lift that make the big difference, you could also run a a little more weight towards the front on the corner balancing as well

If you look into introducing more "rake" towards the front you'll get more grip there etc

thanks I'll look into that.

Once I get this sorted for now I will obviously continue to evolve and better it. Next will be expensive items needed 6sp, turbo and engine etc

If you have the TY754NAAA box (may have missed a letter ha)

It will probably hold power up to what I'm running, mine was fine, the clutch went and decided to switch to 6 speed as there was supposedly a lot more left in the map on the car.

Are planning on an ECU?

Currently most has been fitted but the kcl30 for front did not fit. I need 10mm.on arb side and same on chassis side so have had to order another solution as they had no kcl32 in stock. From 22mm arb on soft and rear 24mm on medium. Will see how that goes with rear suspension set on mid damping instead of full hard.

Sti lower arms are the issue assuming it's the front ARB drop links?

Those are for the WRX

Mine had similar fitted and slightly twisted they would fit

Got the adjustable ones by super pro now, still not ideal mind as the angle isn't quite correct but it's better than a mount constantly under pressure

Just fit in required holes with no tension. (You would probably not be able to get tension on the fiddley wee *****) If you have steel arms as above the others wont fit.

Ive done it zero pressure with the suspension fully compressed

I've gone for the adjustable rear arms by hard race so I can run an adjustable rear drop link as well

My fronts

i suppose I could make two little slices of bar to sandwich and straighten the bottom part of the link

​​​​​​That's compressed

I think I'll set about cutting some bar to take the angle out

Another thing on the the never ending list

If you zoom in it's just the little bit you can get a spanner onto not threaded

It's an annoying issue

I think the standard ARB has the the ends angled to match the lower arms

doing a small session at the end even with power alot lower and loads of lag due to the exhaust side leak and fueling being all over the show i still managed to be a few seconds quicker. cornering felt better, definately more weight on front end but still work to be done and adjustments to be made.

I can't mind now. Will need to chdck again but I think it's up above on thread. Pretty much the same as what yours was apart from toe in at front and out at rear which I want to do. Tyre wear was even so camber is good. R888r were screaming at front and getting squirmy

Toe out front toe in rear
i ran toe out toe out but it was all over the the place

I've not tried toe in front and toe out rear, I'd imagine that would not be a good set up lots of push on turn in followed by over steer
Nothing wrong with trying it though

Also r888 are sensitive to tyre pressure

What were you running

I want to try the AR1s or the new maxsport offering when my tyres are done

Hi matey, stupidly unsure of pressures as left it at home but had it at 28psi I think cold.

I'll go with that above you mentioned, I need rear toe adjustment bolts?

Also going to try a vf24 setup with 48 compressor rebuild.
I think slicks is the only way, really makes the subaru. If dry of course. I've the gasket ordered for uppipe. Thinking of a venturi setup uppipe.

Need to be monitoring what they get up to hot mate, I've not run 888s but I'd imagine 30-32 hot would be decent

In the vids it looked grippy then like they went off towards the end of each short session

You've got toe bolts as standard, they should be able to to get you the toe you need if not it's adjustable arms

That turbo will be interesting what sort of power is that expected to make?

It's never been done so unsure maybe 350..nobody has done it I think. Small exhaust driving a large compressor may be a problem but this uppipe and being in high revs may be OK. Also could try port headers.

Yea need to order a tyre pressure monitor for the track day. The 888s defo got squirmy on hard brakes and mid corner but atleast there was feeling now.

Order one asap ha
can guarantee you'll have gone way above with the pressures

I've not used 888s myself, so do some research on they like to run "hot" pressure wise

You can play around with slightly more pressure rear than front or vise versa

I tend to run pretty even though

I was considering the sc36 but now think I've settled on a vf24/48 or maybe even 50 compressor billet ball bearing for a nice power delivery and power range that suits the track. I am not after numbers just lap times and don't want lag at all to help the corner delivery.

Also considering a 2.5, just needs to be strong. Who does a strong 2.5 or was there any oem strong?

none of the 2.5's were strong out of the box.

Speak to Alyn at AS Performance* re building a strong one. He does all sorts of kit and machine work for Subarus including CDB inserts, 14mm stud and rear thrust conversions along with all the choices for internals and ancilliaries.

Failing that try Paul Finch. He's also on here and has a great reputation.

*No, i'm not sponsored by Alyn!

@DDS789 your turbo, would you know roughly how big the exhaust side is on it in comparison to a vf24? Speaking to craig i think i have a turbo idea to try that will give power but also minimal lag- vf24 exhast billet on ball bearing and 50mm compressor. wtih this ill do a venturi uppipe to aid flow and gas speed. ££850
