I recently had this installed, by RR Racing!! Thanks Rafi you rock. I'm holding off on the review of them alone, as I also had RR Racing Penske Coilovers put in so I'd like to get it to the track before I start complaining or raving about it.

I have not put on many miles on it as my camber is off on one side, waiting on some adjustable bjoints to correct it and I'll give it a proper review, but from the initial feeling... car does feel like a proper handling/race car

Quick update, when I was installing my headers I took the opportunity to re-lube these bad boys to try and alleviate a creaking noise I was getting going over bumps before they got warmed up. I'm happy to report that I used some energy suspension formula 5 prelube on the bushings and steering knuckle and all sounds are gone. It rides like butter now and no noises. Very happy with the results.

I am really sorry you had to do this, please send us an email as i would like to link it to your order date so we can see if we can link it to our assembly dates... Formula 5 prelube is really the best, that is what we use, and it should be noise free for a long, long time.

Very happy with this setup. Noticeable improvement in the response of the front end and much more stable over dips.

Time to chime in - I've had the bushings on for almost 2 weeks. No noticeable increase in NVH, on the crappy roads of CT. Steering is much more precise and braking is more stable. Installation was straight forward - Don't use ramps!

So is the consensus that these definetly help with the inner tire wear?

I would say yes! I think it helps the inner tire issue that is caused by the stock bushings deflecting under load causing the car to toe out I think? Great Mod!

Sounds good. Tired of buying tires. Maybe my wife will buy that. It is actually true this time.

Yeah it's a great mod. Best notice was under hard braking

Rafi[/QUOTE]

Hi Rafi, woild it be possible for those of us who drive in more of urban environment aka concrete jungle lol to create perhaps three levels a street 90duro, a street&track 95duro, and a full on race at whatever level you set.

It seems like large percentage of ISF drivers use them as DD like me. I commute from a suburb of New York City and drive 5 days week down to 34th street in midtown Manhattan using some pretty rough roads, expansion joints on highways and bridges raise plows, potholes, uneven road surfaces you name it.

For those of us who drive in more of urban environment and use our car's as a daily driver a less aggressive 90 duro would work well I think it would be a great compromise between performance and comfort it would still be a vast improvement over OEM set up.

Thanks again for all your great work

haven't logged in awhile on here due to crazy work schedule, ive stopped driving the F here on the out skirts of Chicago. its just too damn harsh on these roads. i hate to say it, i dont enjoy driving the F anymore. im thinking of going back to stock bushings or trading in for a GTR , m4 or maybe even the new gt350r mustang. i want to love my car again and need to find a solution.

I definitely wouldn't recommend a GTR. Too big/wide of a car and much harsher than the F. Good luck parallel parking a GTR
I like the m4. My only gripes are longevity and the engine/exhaust note.
Can't lie that the 08 Fs drive harshly. But the exhaust note is enough for me to love this car even if I replace the coilovers with lead blocks.
I'd stick around with the F for a little while longer just to see if the aftermarket brings anhthing new
