How-To: CP Racing STB in a P5

Every pic I've seen of this Strut Tower Brace installed has been in a Mazdaspeed with no cruise control. It was a long, ugly journey getting this thing in, so I thought I'd save anyone else who buys one the hassle of trying to get customer support from CP. In bold are the instructions I got from EssentialSpeed after whining to them for a week.

Tools you'll need:
1.Flat head screwdriver
1.Phillips head
4.Sockets in 10mm, 12mm, 14mm, and 17mm & a ratchet.
1.Power drill w/ a 3/8 in bit
1.Dremmel w/ a cutting wheel
4. washers with a 3/8 inch hole in the middle of them
1. Open ended flat wrench in 14mm
2. zip-ties

1) Remove wipers and black plastic tray
-Use a small flat head to pop off the tabs at the base of the wipers and use a 12mm socket to remove them.
-Pop off the oval-shaped covers on the plastic tray near the wipers, being careful of breaking them. Use a phillips head to unscrew the two bolts underneath. Careful! They screw into plastic and it's easy to strip.

-Take off plastic tray. Unhook the weatherstripping at each end, then push up from below on the plastic clips to remove the weatherstripping from the plastic tray. This will also unhook the tray from the car.

2)Remove factory strut brace and A/C bracket
-Use your 10mm, 14mm, and 17mm sockets to unscrew the factory STB and all its attachments. Take the black brackets off, too.
-Use a 10mm to remove the Cruise Control unit from it's bracket. Set CC unit aside.

-----------------------------------------------------------------------------

-Use 10mm to remove lower bracket from the face of the strut tower on the driver's side.
-Use 10mm w/ extension to remove A/C bracket from the center of the firewall.

----------------------------------------------------------------------------

-Remove the A/C bracket from the A/C lines. Cut the plastic tabs if you have to.
-Keep all hardware, BTW.

3)Remove all other solenoids from their bolting place.
-Use a 10mm to remove the solonoid on the driver's strut tower, and there should be another one sitting between the strut tower and firewall on the passenger's side. It came off when the stock brace and black brackets were removed. It says Mitsubishi on it.

4)Set the CP Racing STB in place and mark the firewall where you'll be drilling.
-I used a Sharpie to mark where I was drilling, then I busted out the drill and made a 3/8 inch hole on either side. Don't be scared, your new STB is gonna make a big difference!!
You can see my unfinished hole with some ink next to it. Start small, then work your way up to 3/8 inch. You can also see some red paint from the STB. Be careful, the paint on the brace is thin and easy to scratch.

-------------------------------------------------------------------------------

5) Attach Cruise Control to it's new bracket and place the bracket onto the existing bolt on the face of the strut tower.
-This part gave me fits. Pay attention to it's positioning in the pics, and you'll be alright. (screwy) Use the nut from the "lower bracket" you took off earlier.

-----------------------------------------------------------------------------

6)INSTALL NEW BRACE!
Now we're getting somewhere. (spin)
-Slap that puppy into place. Be careful because the paint on the bar is easy to scratch.
-Feed the 3/8 inch bolts that came with the bar(with the washers that you have to buy) on either side through the firewall and use a 14mm socket, your 4 washers, and a nut to bolt them into place. Don't tighten it all the way down just yet.

----------------------------------------------------------------------------

7)Tighten all the nuts and bolts
-Get all your wires and lines out of harm's way, and tighten down your new STB, at the firewall and at the strut towers. Easy does it on the strut towers. I've heard some stories about those bolts breaking off. At the firewall, crank 'er down pretty hard using your 14mm socket and 14mm flat wrench. Zip-tie the A/C lines to the new STB; unless you can find a better, cleaner way to keep them positioned.

8) Re-install all solenoids.
-I used a Dremmel to cut the bracket on the passenger's side. See pic for how it should look after you've cut it. (Yup, there's a couple of fitment issues with the bar blocking some of the mounting holes.)

------------------------------------------------------------------------------

-On the driver's side, the new STB seems to hold down the bracket pretty well....Lol, that's my way of saying that the bar is blocking the hole that we're supposed to screw it back into. Oh-well. I'll have to get back to you on that one, but for now, I'm just gonna leave it as is. It seems pretty damn solid.

--------------------------------------------------------------------------

9) Now it's just a matter of tilting your cruise control out of the way while not pressing down on the A/C lines below it too hard. It's kinda tight, but doable. Just fiddle with it.

10) Put your tray and wipers back on. Position the wipers as close to where they were on the windshield as possible. Make sure they don't wipe the plastic when you turn them on. Also, be really careful of the oval-shaped plastic tabs. I broke one trying to pop it back in. Those little things are super brittle.

You're Done! (rockon)
Go hit some corners and feel the difference! The car really seems to track better on the straights and the turn-in is instantaneous. (thumb)

Questions, comments and criticism are always welcome!

Very nice, ive been lookin at several different STB's and cant decide really, how would you rate this one, I know you said it was well worth it but how much of a diff, in your opinion, did you notice?

Thx
Great How-To.
 
Last night, up on Hwy9 I noticed a difference in the turn-in. The car seems to just dart wherever you point it now. Also, I noticed that the car seems to want to go straight a little more than before. I lost some of that tracking when I installed my coilovers, but this bar seems to have brought back some of it...and it's more than welcome back!
The worst part about this bar was the ordering process. Between the month wait and the lack of any instructions/customer support at all, I was getting pretty frustrated. Hopefully, this How-to will alleviate some of that stress for you guys. :)
 
so then where did you get it from and if you dont mind how much, and was the month long wait due to the retailer or cp racing?

Thx for the info, again great howto, usefull for any STB install.
 
Thanks for the write up Nate. From the looks of the pictures those holes on the strut tower look like they don't fit at all, or is it just because this is before you tightened them down
 
sounds like its a mediocre company at best.

oh well. i was going to get one of these but until they can get their s*** together or another company produces a more high quality piece i guess i won't.
 
Good write up Natey! However you might want to be careful about this. I believe that circled piece of plastic is an airbag sensor. You wouldn't want that to come loose and flop around in there.You also want to make sure it's mounted in the same orientation as stock. Or else bad, bad things could result ;) .

Whoa, Thanks for the info, thewrench!
That could be ugly, indeed.
It's actually in the OE position and the brace is holding it down, but I'm still a little nervous. I tried like hell to get a screw in there, but the brace is in the way. I may take the ol' Dremmel to the brace and make room for the bolt.

melicha, the holes are actually slots. They make a little leeway for positionong the brace.

Get out the drill and just put a new hole in the fenderwell. Nut and bolt and no worries!
 
Good idea shinzen. This club is the best! I love how you can get a ton of different opinions and theories just by simply asking.
What you suggested is so simle, but it hadn't even crossed my mind. Tomorrow, that's first on my agenda. (spin)
 
Thanks Nate! great write-up. I still have to put mine in, maybe this weekend.

Do you still need me to order you some tabs when I order mine or did you get yours out without breaking them?
 
thanks natey... now i know what to expect. how does the red look? is it close to the stock's red?

i was going to suggest dremeling the STB to make it have indents for the holes it is covering up, but you're already on that. good job and thanks again!
 
It seems a tiny bit darker colored than the stock brace, but it looks pretty good. No complaints at all now that it's finally installed. :)

You going for red, too? (rockon)
 
nice write up!

looks like the screw holes on the 3point strut bar are too big/off centered..? - chris

i dont mean to be so anal... but how come the metal looks jagged? - chris
 
lol, because CP Racing is run by a bunch of Jr High metal shop students? :D The paint/weld/cut quality could be better, but this bar really makes a difference in handling.

Also, the holes are actually slots. They make a little leeway for positioning the brace.
