Pettit launch kit install
 
I got around to installing the rest of it today while sick at home. Here are the pics, went very smooth. People where saying I had to drop the whole rear end to install the Diff mounts but I diid not have to. Was able to just unbolt it and remove it and install the fresh mounts. Very easy. But after 157k mils it needed some new parts.

Cars has a little more road noise but I can live with it, just got a few more bushings to go. Going for 11's tihs year with her. Best last year was a few

Nice work. I just did mine and also snuck the diff cradle out by just lowering the diff. Your stock diff bushings must've been frozen in there pretty good. What you call the "LCA" is actually the trailing arms. I went with different parts though, Mazdaspeed trailing arm bushings, Superpro diff and toe link bushings, and brand new pillow balls. Also have a Banzai diff brace.

Do you have any kind of diff support? I'd be worried about breaking the ppf or diff getting into 11s. Have you checked out your pillowballs also? Those wear frequently and cause noise and probably toe-in/toe-out.

LCA is trailing arm thanks, guess I should'nt be posting at midnight. If someone could fix that i'd thank them it wont let me edit my own post...

may sound stupid but how does it help the launch?

AHarada 01-14-09 01:39 AM

My guess is their logic is the deflection in the old wornout OEM bushings causes toe-in/toe-out which causes wheelhop. And also the fact that the OEM diff bushings have quite a bit of play in them especially worn ones.

FD3S2005 01-14-09 01:59 AM

and what is the diff between getting harder bushing and these, besides the fact you dont need bushings

muibubbles 01-14-09 11:17 AM

can you help me? how do you push the diff bushings out? i dont think im pushing them at the right point.....

given i was using a 15 ton press, when i pushed on them they were kinda spongey and felt like the were flexing/bending rather then poping out.. i stopped after that getting worried if i was doing it correctly... is that how they start off? or should it be a solid push through out?

where does the license plate border come in??

If you look at my picture's you can see that there is a metal ring inside another ring, they need to be pressed apart. Dont put pressure on the rubber at all.

It came with the kit, I guess I need to do a license plat instal thread :)

How did the car feel after this install compared to before? Just increased road noise?

Feels better I actually felt the car lift the front end today when I got on it for a secound, it use to just squat. Shifting between grears feels better to. I still have clunking noises but thats form the Control arm bushins I need to replace next. I installed the endlinks and trailing arms last weekend before the dif bushins and I noticed the rear end did not swing out as much in corners. My car has 157k so it needs some tlc ing the suspension dept.

figured... after reading the bushing install thread it recomended to use certain size sockets to apply pressure on the right parts, did u use anything to apply the pressure over the outter ring?

AHarada 01-14-09 06:40 PM

I don't believe you need to tear apart the old diff bushings to get them out. If you use the right size socket or press tool, then you can take the entire bushings out of the cradle in one piece. Most are frozen pretty good inside after all the years of abuse. Try soaking the bushings in PB blaster, maybe some may seep between the cradle bore and the bushings and they may come out easier. Most likely, you're going to have to "pop" them out since they are stuck in there, then they will come out easy. Just like a bolt that's stuck on.

adamrx7 01-14-09 06:42 PM

I put a few tall sockets around the bottom outer edge so the bushing woud have a place to go. I guess I should of taken some pics while at the shop.

I did exactly the same thing - my old bushings came out completely intact.

I put the new bushings in the freezer the night before, they pressed in easily, no binding, no problem.

know what size they were?

wow man it's not that hard. They where random sizes, the important part was they where all the same height. I used them as "stilts" to give the old bushing room to slid out. Kinda riged the whole setup.

You might also want to update your profile so we know where you live. If you where in STL I'd press them out for you.

So about a month ago I added the launch hit to help with some of the bushings and toe links in my 160K FD, This did not stop my mayjor clunking noises but did help the feel of the car. This week I added six new pillow balls to the rearend. Theses fuckers are expensive, $62 a pop at cost ($100 retail). They fixed all my noise problems from taking off to slowing down. Here are a few pic's of the destroyed pillow balls. Lets just say I got about 70k more miles out of these then most people do.
I installed them in about three hours in the garage.

Next week poly motor mounts :happyguns

Big thanks to Ray Crowe at Malloy Mazda for the great customer service and speedy delivery.

adamrx7 02-27-09 01:37 PM

So I installed the Motor mounts last night. The car feel ALOT better. And I think I got about two inches of slop back to a nice shifting car. I hope this helps the third gear shifts, it felt like it did.

not much to look at on the car

I have alot more vibration with these but it's a good trade off for the better shifting. I'll see how they feel aftr a few thousand miles.

Thanks to Banzi Racing for getting these to me in three days. Great service.

staticguitar313 02-27-09 03:21 PM

have the same motor mounts i do love them, very large improvement, the slight addition in vibration transfer is a trade-off thats worth dealing with.

fendamonky 02-27-09 04:47 PM

I can't wait for mine to get in. The other week I ordered Engine Mounts from Banzai, and the Launch kit from RP.

I received the Launch kit a day or two ago, and am now just waiting on the engine mounts (big thanks to the Military Postal Service for the delay!! lol)

Your old mount was BEAT!!!
