After all of these years of reading Racecar Engineering, I had to have the trick stuff. To me that means the shock has to be mounted upside down. The factory F40 mount is a pin on the top. I wanted this to be changed to an eyelet. I also wanted to have access to the mounting bolt from the top. An Ohlins would fit, but I would not have access to the mounting bolt from the top. Rob, I got your message , Thanks. |

John, I'm glad it was your first choice :-)
I'm surprised that he couldn't get those parts, did he check with Ohlins in sweden? The guy on the second link build any Ohlins damper for any car.

John,
I emailed you at the address in your profile.
I'm out of the office Thursday, call my mobile, back in Friday.
Thanks |

Peter, Ohlins were my first choice. I insisted that they be mounted upside down and the US distributor could not supply an extended body cap and eyelet. Also, he didn't like the fact that they would see so many street miles. I have them on my 996 SPS Ducati and I love them. Penske's were my second choice. |

Check Ohlins Racing shocks. Mark E. (2nd post) knows more about them.
Check http://www.ohlins.se/
I have them on my 328. Check pix at http://www.stotdamparexperten.nu/efter.htm

Well, it's not yet a done deal but the dry builds are on the way. Tell my about your product since I know that the damper industry is like anything else. The guy with the good ideas leaves and starts a new and better company, better product, but lacks name recognition. I am interested and I'm sure that others would benefit. I'm interested in 3 or 4 way adjustables, inverted mounting, and adjustable spring mounting on the shaft and body end. I need extended mounting eyes on the shaft and body end. Also need metric spherical bearing mounts on both ends to accomodate an F40. Do you have a web site? Thanks! |

Hi John,
Hey, I could have saved you $1,200.00 on your damper set-up.
We have not dyno'ed the new Koni four-way, but if they perform similar to their older designs, it will lack in range of adjustability, and consistency in matched pairs (difficulty getting two to perform the same).
Penske's are nice, though be careful, what you think you're adjusting, you're really not in some cases, and end up confused.
Send me an email and tell me about your car. |

The MOI for the 3 plate C-C clutch is almost identical to the 2 plate metallic. This is due to the fact that the C-C clutch uses a 12 bolt fixing and the metallic uses a 6 bolt fixing. This is for the 7.25 inch clutch. The Tilton billet steel weighs about the same as the AL one that was shown in FORZA. For the same price, you can have the C-C clutch and flywheel or the metallic 2 plate and Al flywheel. I'll take the C-C any day. When it comes to C-C clutches, Tilton wrote the book. Rob, what do you think of the new 4 way adjustable Koni's ? I just ordered some Penske 3-ways. |

Norwood has Centerforce applications for TR, 348, etc.
As for C-C on the street, forget it. I had Tilton design the F40 application for a race-only car. It was like adding 50 hp due to reduction in moment of inertia (M.O.I). Very durable for racing, but a pain in the *ss for street. I know 'cause I'd drive the beast on the street for shake down before loading on the transporter. |

I've replaced them on a 3x8's as early as 3000 miles because people ride them too much. Then I have seen them with over 50K miles on them. Driving habits can make a big difference. |

Bob,
Yes Maintenace is the periodic adjusting of the clutch. Each bit of wear on a 3 series clutch, because of the design of the levers, causes the T/O bearing to apply more pressure on the PP which prevents it's complete release, causing overheating (increased but not felt slipping) which leads to Very Premature Failure.
The clutch adjustment should be checked and adjusted as necc. at least with every oil change(5K-7K miles).
I've seen many instances of drivers running with a tight clutch completely unaware it was burning up their disc. |

Don't worry Bob, for a clutch to wear out a car has to be DRIVEN! :-D |

***Single biggest cause of 3 series clutch wear is improper/lack of maintanance!***
JRV, can you describe "improper/lack of maintenance" on a clutch??? Are you referring to clutch adjustment... or are you referring to people who don't know how to drive and slip the clutch? What "maintenance" needs to be done on a clutch? |

Don't feel so bad Paul. That TR I'm working on also needs a clutch. Priced it from Trutlands...guess what it cost? With the exchange it came to $3700!! |

You can get your AP clutch rebuilt for a fraction of the new price . Call Truechoice. If you don't like the AP clutch you can get a Tilton direct replacement at half the cost of the AP. I don't know why you would want a big heavy centerforce when you can have that cool AP clutch. If you really want to end your clutch worries, get a Tilton carbon-carbon for $3700. |

I want to find a clutch manufacturer or rebuilder(dont flame) to see if it can be identified or matched to something else. I dont mind paying $1000 for a clutch as lond as its a good one that I can use hard without clenching my teeth for fear of hurting it. The kevlar route is an option provided chatter isnt an issue on take off. |

Im questioning the durability of the stock AP clutches. 40K isnt very far for a $1000 clutch considering I dont side-step it, launch hard or spin the tires. It should last 150K like any other import or domestic. The life of the car actually. My old civic Si has over 350Kms on the original clutch, how? Why? Because it isnt crap. I like the centerforce clutch mod Ric. Ill look into it further. If AP makes racing clutches, I probably wont like the price if the stock one is overpriced. |

JRV wow $1500 for a transam. I guess I need to raise my rates.I gota believe you are going with racing components here and that the parts cost is somewhere around $1000. Also assume you replace the flywheel? I can see more clock time in taking down the 308 but for a inline V8 with a 5 speed its pretty straight forward somewhere around 3-4 hours start to finish.So even at $100 an hour its pretty cheap. |

Single biggest cause of 3 series clutch wear is improper/lack of maintanance!
I've seen MANY go 40K miles when properly driven & maintained.
AP makes Racing Clutches! www.apracing.com
what's with the name calling anyway?
one of my customers had the clutch replaced in his 90's Trams Am and it cost more for that job ($1500) than I charged him to put a new clutch in his 308 ($1300) using all the latest 328 parts! |

Actually, I have had two 308's with Centerforce mods on them. Take an OEM pressure plate and send it to them and they'll add the weights. On one car I put 18K miles and the stock disc showed less than 15% of it's allowable wear. |

I bought a clutch from Butch at italia design, heavy springs, kevlar disk, $600. He said the shop that made them for him could set them up any way I wanted. It's been fine. |

This is an off shoot from the 328 clutch thread. I would like an alternative to buying a $1000cdn crappy AP clutch for my 308. I wish centerforce made clutches for ferraris. They are 10 times what any AP clutch could ever dream of being and cost less than half the cost. Has anyone tried to match a ferrari clutch to another european make of car like an alfa or something. Something without the "ferrari" price where you actually pay what it is worth rather than an inflated price for garbage? I cant see ferrari specifying a unique clutch for their cars for mass prodution. |
