My mom has an '89 CRX Si, and it doesn't have rear discs. Was '90 the first year? Thanks. PEACE OUT!

 

yes.

 

I don't think it was '90 it was '91.

 

'90 Si I believe...

 

I'm almost positive the 90-91 crx si was the only 4th gen crx/civic with rear discs (unless the EX sedan had them).

 

i have a 90 and a 91 crx si's, they both got 4 wheel disk brakes, these 2 years where the only ones w/4 wheel disk brakes.

 

correct. 90-91 crx si have 4 wheel disc. however, i have yet to see a 4 wheel disc sedan. i have heard that for larger rotor upgrades on the front it is necessary to have the EX sedan front hubs, but i have not seen any yet.

 

Thanks for the replies. I imagine it's fairly easy to convert an '89 to the '90's rear disc set-up, right? Can someone please list all the parts I'd need to snag off a junked '90 CRX to do this. Thanks. PEACE OUT!

 

If the swap is from CRX to CRX you will need the complete rear arms with spindles, caliper, rotors, e-brake cables. If its for the hatch the CRX e-brake cables won't work. You will have to get the cables from the 90-93 teg. The complete rear arm assembly from those Integras will also work. I have 92 Teg's on my hatch.

 

Thanks for the replies again. I want to buy better rims for my moms car, but we can't have those rear drums peeking through the rims, now can we?lol. Looks like I need to do the rear disc conversion first. Thanks again. PEACE OUT!

 

Is it worth the effort and time for this swap, or should i just keep my drums?

 

It depends on how much power your car is making. If a lot, you definitely might consider upgrading your braking system, if not, then I wouldn't worry about it too much as the drums will be enough.
