I'm going to be doing a 5 lug conversion on my car and I'm looking for some input from anyone that has a 5 lug crx. Is it worth it? What are the pros and cons. Thanks in advance.

 

5 lug has different wheel options. But if you want to stick with 15 inch or smaller wheels, retaining 4x100 is your best choice. The 5 lug ITR swap also uses bigger, more durable wheel bearings than the stock civic and crx. But you can also do an integra 4 lug swap at all 4 corners and get bigger wheel bearings than the civic/crx.

My personal opinion is that you could better spend the money elsewhere and that, performance wise, you don't need that extra lug.

 

You also get huge brake rotors and calipers... more options for aftermarket calipers...

my HX went from stock brakes with drums to full Integra discs and it feels completely different. I'm sure an ITR setup would do wonders for a CRX - the weight increase IMO is well worth it.

 

Thanks for the info guys. I'm actually acquiring the ITR 5-lug plus regamasters in a trade and I might as well use it. Will post pics once it's all done.

 

Just remember to change the prop valve and you may also want to look into upgrading the master cylinder as well to match the braking system. Not 100% for a CRX doe

Got it. Thanks much guys

 

If I recall, DC knuckles don't fit a CRX/EF.

 

you are correct. technically they do fit but they will require you do lower your car due to massive amounts of positive camber. it will also throw off the caster as the knukle is moved toward the back of the car slightly.

not recommended as the UCA will be hitting the top of shock tower.

 

if you really plan on going 5 lug... i would recommend using either the DA or CRX SiR knuckles. once you have these knuckles in your possession then all you need to do is get some ITR hubs and have them machined to fit the bearing. or you can get custom made ones like i did.

pm me if you would like more info. i have done this conversion 1st hand and not just speaking from passed down stories and rumors.

 

Pm'd

 

I'm still with the previous guy that said use 4x100 DA knuckles. Get rear discs too. That's basically what I did.

 

Thanks guys. I already have siR front knuckles and rear disc

 

It also depends if.you get the 36mm or 32mm hubs... the 32mm hub you can use you stock front spindles and press the itr hub in. I am currently doing this on my 90 hf and using just a crx si 40/40 prop valve. 32mm itr conversion is wayyy easier than 36mm for the efs

Pm me if still interested in more info

 

I would say you are wasting your time and to sell the wheels. Sir knuckles are decent already. DA is the setup of choice unless it's a track car.

 

Just get the Sir Knuckles machined to fit the barrings and that should be the easiest path.

 

If you are using 32mm 5 lug the hub will presses straight into a normal civic wheel bearing.... no machining required. 36mm hubs require the machining.

 

5 lug set up weighs like 25 lbs more than stock 4 lug, and almost requires 16s...how did the ctr get away with 15s? Calipers not big enough or what?

 

i'm swaping to itr 5-lugs too... if i use camber kit in the front with the itr knuckle its fine??

 

Would you please post more info?

I've done the 5lug conversion the "wrong way" on one of my EF's - by using the itr knuckles and simply bent them a couple of degrees in a press.
I did it this way because I also retrofitted the itr abs system.
Obviously these knuckles are a little bit taller than the original EF knuckles - so if you slam the car then you could have clearance issues with the underside of the shock towers.

The best way is DA knuckles (IMO) if you want a bolt on solution for optional abs retrofit.
But I haven't found an ideal solution for the knuckle - having it overbored in a jig so as to fit the itr bearing is the best way to go about it - but to have this done correctly and reliably is a crap shoot.
Another solution is to simply fill and drill the da hubs so as to convert them to 5lug.
The last solution would be to have an aftermarket hub made that has the same dimensions as the da hub, but which is drilled for 5lug.

my crx is 5lug as well and I went with ds spindles and da bearings with machining down the itr hubs
