I Need Help! !! Xt130 Coilovers Pug/hilux Brake Upgrade

[ke35 dan]

Hi I have just bought a set of xt130 coilovers with the pug/hilux brake upgrade, cusco camber tops, ae86 p/s arms and 40mm rca's for my ke35 coup. My question is WHY DON'T THEY FIT? the rota is hitting the lower control arm. I have trimmed the control arm down and it only just fits without the 40mm rca's. With the rca's the lower ball joint bearly fits. Has anyone actually fit and driven a ke×× with this configuration or was I jiped? Am I missing something? Do I need a custom lower control arm. Pleeeeeasssse help me ive been building this car for over two years and just want it finished

You need XT130 LCA's and lots of camber, or NCRCA's. Alternatively you can run XT130 steering arms with the ball joint hole offset, though they are longer and will decrease lock and steering response.

 

EDIT: I had the same issue and I use XT130 arms, but its not built for drift and gives me lighter steering.

Thanks mate. Ill look into xt130 LCA's and steering arms. Sorry to noob it up but what are NCRCA's?

[B.L.Z.BUB]

Negative camber roll center adjusters. They bolt in like normal RCAs but offset the strut further out from the LCA.

 

 

If you don't mind camber just run XT130 LCA's and camber the ʞ©$ɟ out of your camber tops. If you don't mind lighter. slower steering with less lock just use XT130 arms. You wont need both.

 

If you use the NCRCA's you can add some positive camber with the camber tops and all it'll do is increase the front track, so you'd have the issue of more poke from your front wheels.

 

XT130 steering arms will give you approx 10mm more poke.

I found on my ra40 based coilovers the control arm only interfered with the backing plate with xt130 lcas, I was able to pry a couple of mm clearance easily. I had NCRCAs there just in case but they weren't needed with the ra stuff. I was able to use ae86 steering arms and normal 35mm rcas.

 

You shouldnt remove metal from or modify your control arms, at least on the street.

Agree'd. I actually massaged my LCA's with a hammer first. Still nowhere near enough clearance with RCA's.

I did talk to T3 and they say they can make their AE86 steering arms with an offset balljoint hole the same as XT130. I'm wondering if I should become the guinea pig and pay for them to do it.

 

EDIT: I am going to email them now and get the ball rolling.

Thanks guys. I agree, I didnt want to mod the control arm. And regretted it straight after I did it. Are the 40mm rca's to big? It seems the further away the control arm is from the base of the strut the worse the problem is

The RCA's arent too big. You just need to find a way to offset the rotor. I got an email from T3. If I can find ten guys keen they will make a batch to suit.

[ke35 dan]

So the xt130 LCA's showed up yesterday. The rota still fouls on the lca the only difference is the now ridiculous angle of the lower ball joint. And thats with the adjustable camber tops. I think offset steering arms will be the next option

Can you take some pictures of your problems?

 

i have run this setup for 5 years and never ran into this problem.

[LittleRedSpirit]

Put up a pic, and are you sure its not just the backing plate rubbing the end of the lca, I was able to pry it back away with ra40 gear and I realised I only had an issue at all because the tin rotor covers were bent a bit.

[ke35 dan]

Just pulled out the "xt130 lca" and put it next to the ke35 lca that I've ground down, and they look the same size? Aren't xt130 LCA's ment to be longer. I bought these off a guy here on rolla club. There isn't a backing plate on the rota, its the disc that is hard up against the lca, to a point where I wouldn't try thread a bolt through

[B.L.Z.BUB]

You can make it work without RCA's as stated but When you add them into the equation it pulls the rotor further in towards the lca. When I tried with 86 arms the rotor was fouling.

 

Are the pug discs meant to alleviate this issue? If so you may have stock xt130 rotors. I can't remember if the pug hilux setup was meant to fix the lca clearance issue or not.

[LittleRedSpirit]

KE30 and xt130 lcas are the same length.

 

Always have been. They are both 10mm longer than ke70. Same as RA40 and rt132, and maybe even ra65.

[B.L.Z.BUB]

Oh shit that's right, spot the guy who only thinks in ke70s. can't lose money on them at least.

 

In that case you could run ke70 lcas and NCRCAs without worrying too much about extra track. Then the 86 arms will work fine. This set up is what I'm looking at doing except I can't find a lca shorter than a ke70 one to use.

 

Then you can sell your ke30 lcas to the ke70 boys for mega takumi tax prices.
