Im considering getting modified Knuckles as well as lower control arms which are lengthened by 2cm.

Im wondering, do i need to modify anything else to get it to fit. It seems that if i move a suspension component 2cm outward, shouldnt that mean that other parts wont line up?

Any other considerations or hidden costs etc when doing this modification? FYI Im also ordering Kazama tension rods which will give more clearnace if im really cranking the steering angle.

thanks

You'll get alot more camber up front. I'm running something like -4.5 with 20mm LCAS.

everything should line as as long as the cut and shut has been done after the castor rod position.

Just make sure you have a wheel with some inner clearance (i.e 8-9 +20ish) and you should be sweet. Worst case, you can always chuck on a spacer.

Might want to grab some upper arms so you can adjust camber accordingly. Obviously when you lengthen LCA's you will have a whole heap of negative camber because you would have pushed the bottom out.

definately get upper camber arms wouldnt be doing the above without them !

also some people have found that you need longer tie rods ... i have knuckles and r33 lca's and 20mm longer tie rods and there is really just enough thread to make it safe, some people have bought 30mm longer just in case, depends on your exact setup though

Im doing my knuckles soon and I have bought a set of ikeya tie rods they are massive so they will be enough but yeah as for the rest as others have said need camber arms to bring back the camber.

Lengthing lca wont give you more lock it just gives you more clearance from rail and castor rods so you can run more lock.

So it depends if your current problem is clearance then yes you will gain lock providing lock stops are cut down but if youve maxed the rack travel thats when youll need the knuckles.

as above.

I did get more lock with the inner/outer tie rods but yeah the LCAS are more for clearance.

I want to cut my lock stoppers on the knuckles down, I should do it this weekend actually! haha.

      It would be well worth deciding where you want to go and what you care about. Reliability of everything in a 34 drops MASSIVELY above the 300kw mark. Keeping everything going great at beyond that value will cost ten times the $. Clutches become shit, gearboxes (and engines/bottom ends) become consumable, traction becomes crap. The good news is looking legalish/actually being legal is slighly under the 300kw mark. I would make the assumption you want to ditch the stock plenum too and want to go a front facing unit of some description due to the cross flow. Do the bends on a return flow hurt? Not really. A couple of bends do make a difference but not nearly as much in a forced induction situation. Add 1psi of boost to overcome it. Nobody has ever gone and done a track session monitoring IAT then done a different session on a different intercooler and monitored IAT to see the difference here. All of the benefits here are likely in the "My engine is a forged consumable that I drive once a year because it needs a rebuild every year which takes 9 months of the year to complete" territory. It would be well worth deciding where you want to go and what you care about with this car.

      By "reverse flow", do you mean "return flow"? Being the IC having a return pipe back behind the bumper reo, or similar? If so... I am currently making ~250 rwkW on a Neo at ~17-18 psi. With a return flow. There's nothing to indicate that it is costing me a lot of power at this level, and I would be surprised if I could not push it harder. True, I have not measured pressure drop across it or IAT changes, but the car does not seem upset about it in any way. I won't be bothering to look into it unless it starts giving trouble or doesn't respond to boost increases when I next put it on the dyno. FWIW, it was tuned with the boost controller off, so achieving ~15-16 psi on the wastegate spring alone, and it is noticeably quicker with the boost controller on and yielding a couple of extra pounds. Hence why I think it is doing OK. So, no, I would not arbitrarily say that return flows are restrictive. Yes, they are certainly restrictive if you're aiming for higher power levels. But I also think that the happy place for a street car is <300 rwkW anyway, so I'm not going to be aiming for power levels that would require me to change the inlet pipework. My car looks very stock, even though everything is different. The turbo and inlet pipes all look stock and run in the stock locations, The airbox looks stock (apart from the inlet being opened up). The turbo looks stock, because it's in the stock location, is the stock housings and can't really be seen anyway. It makes enough power to be good to drive, but won't raise eyebrows if I ever f**k up enough for the cops to lift the bonnet.

      There is a guy who said he can weld me piping without having to cut chassis, maybe I do that ? Or do I just go reverse flow but isn’t reverse flow very limited once again?

      I haven’t yet cut the chassis, maybe I switch to a reverse flow. I’ve got the Intercooler mounted as I already had it but not cut yet. Might have to speak to an engineer

      Yes that’s another issue, I always have a front mount, plus will be turbo plus intake will big hasstle. I’ve been told if it looks stock they’re fine with it by a couple others who have done it ahahaha.    I know @Kinkstaah said the stock gtt airbox is limiting but I might just have to do that to avoid a defect so it atleast looks legit. Or an enclosed pod so it’s hidden away and feed air from the snorkel and below Intercooler holes like kinstaah mentioned. Hmm what to do
