All the upper arms on my car are Delrin. All the lower arms and rear upper knuckles are Spherical Bearings. You don't want Delrin in the lower arms or the upper rear knuckle. They WILL bind. That with solid aluminum motor mounts and delrin diff bushings. You would NOT want to drive this car on the street....EVER....BUT you will NEVER miss a 2-3 ---- again.

I've tried to bite my tongue not saying anything in your little corner, but now that you are in Race Prep trying to push your "good deals", let me make a suggestion...

POST A PRICE OR GTFO!!!!!

I'll never buy from someone who says "PM me for price" just like I'll never buy from Best Buy when you have to checkout just to see the price. I'm sure I'm not alone in this feeling.

Ok I Understand how that can be annoying one of the reasons why we do that is to keep things organized for both parties.
Another reason is we can get a accurate quote including shipping buy getting your full address without everyone knowing where you live exactly. Its not in our plan to be difficult. lol

I may be wrong here. I am NOT a lawyer at all, just guessing. He may not be allowed to post a price. Posting may be under "advertising" it at a price vs if it's a PM it can be deemed "the bro" price. It may be a legal issue with some manufacturers/marketing F-bags. If everyone can see it and goes around ***** nilly saying OMFG he has it at $??? price and you have it at $???? price what the hell? I don't do any marketing myself, but have had friends in the business. I have since unfriended the D-bags. I hate marketing people. Hate. I'm not trying to defend Renown, but sometimes there is a reason.

On a side note.....I do agree with you chpmnsws6 it's F-ing annoying and sometimes the lag in response to a PM may or break the deal to me. Sometimes I'll spent my time waiting for a price searching for another price. Other times I just lay around and touch myself, the time is worth more to me that way somedays.

Talked to a miata guy this past weekend he was saying one derlin mount and one mazda comp is what alot of turbo guys run?

Well, we are "alot of turbo guys" here and I have never, ever heard of anyone doing that here.

That would be great! You can have the softer mount (more movement) of the Mazda Comp bushing and the noise and harshness of a delrin mount! That spells win to me! I heard that adding the ebay hydraulic engine mount support thingy makes it even better and will reduce wheel hop on a miata as well!

I've read this more than once on m.net and CR. People seem to do this as a "compromise" to deal with the "harshness" of the derlin. I'm not saying its a good idea, I'm just saying I've seen it mentioned before. Just man up and run the MazdaComp mounts. They fit and they work.

Hell, what are Savington and Emilio running in their racecars? Last time I checked the 949 cars were running MazdaComps (granted, its been a while) but no clue on Theseus or Rover.

We run MazdaComp mounts in all of our cars (yes, including Theseus and Rover). We have used stiffer but it ends up vibrating the car to pieces (literally, it vibrates bolts loose).

Marine grease works pretty well on suspension bushings. Whatever brand is in stock at your FLAPS. It's green, and pretty seriously sticky.

What is the consensus on derlin vs. poly. I will be tearing into my control arms on my track car next week and still need to order the appropriate pcs.

I've read some opinions so far: Derlin: wear issues? binding?
poly: street soft; not for race?

My ES poly bushins have held up to great abuse. They are an awesome uprade from sloppy stock. I def feel they are track worthy.

The Delrin is even more responsive and awesome. havent had time on them to say how they wear in.
No binding issues as they have a sleeve in them.

As for motormounts I run solid metal. I have torn stock, Megan racing, and mazdacomp engine mounts in half. I did not break the the MMR delrin, but I did almost pull the bolt through the subframe on the drivers side...

This is all at 300-470 ftlbs in regard to power

The Catfish has AWR Delrin bushings all around and AWR motor mounts, which are PU. No changes made yet to the diff mounts.

Many people I've talked to like the Delrin for the track and something softer for road use. Although I haven't noticed, Delrin is supposed to squeak as well.

Mazda hyped that the suspension geometry is such that the bushings would flex in a turn, giving extra toe in. When everything's fresh it probably works, but on the track precision wins out over "plush" IMO.

Here's a video of the Catfish with the AWR pieces:
