A 1500 Miles with NSX type R suspension

Last June I had installed the NSX-R suspension including the front anti-roll bar. Last weekend I drove from Charlotte to BarnMan's shop in Nashville (450 miles) to have the CT non compliant rear beam and toe links installed - then on to Eastern Ohio then back to Charlotte.

This suspension has a wonderful direct response to steering inputs and very flat handling - no roll and no dive on braking. 98% of the time it was comfortable. Because of the progressive springs it actually takes bumps well - much better than my 944 Turbo S with linear springs ( 500 # front and 450 # rear) which banged and jarred on bumps. However there are stretches of roads with little irregularities which sets the front vibrating - and my head boucing up and down. But this is only about 2% of typical interstate highway. On smooth interstate in the mountains it is pure pleasure.

The Comptech non compliant rear beam and toe links did not transmit road or tire sounds into the cabin and there was no clanging from the plastic bushings. But I immediately noticed the handling difference in fast/hard turns. Instead of the rear of the NSX shifting toward the outside of the turn then taking a "set' when the rubber bushings compressed, there was no such movement which I found disconcerting at first. It seemed the rear was steering itself through the turn. Initially it felt like the car was perhaps unsteering because I was accustomed to the body rotation pointing the nose into the turn. But I soon realized that what I was sensing was an absence of the rear end shifting on the rubber bushings and that the rear of the NSX was turning without the usual rotation. It's like the NSX is on rails.

I am looking forward to three days at VIR in two weeks and learning how to control this new animal on the track.

By the way, BarnMan (Barney Demonbreun) did an excellent job of installing the rear non compliance beam and also CT headers. I recommend him highly.

i'm also thinking of doing that modification. How much did that run you?

I bought the NSX-R suspension form SOS for about $1,850 - much less than the $3000+ it used to cost.

I bought the non compliant rear beam and toe links "used" on NSXPrime for $750.

Are you coming down to savannah this weekend for the roebling event??

No, I can't make it since I am instructing at VIR next weekend. I understand that David's car won't be ready for Roebling. Too bad.

Sorry that I won't have a chance to meet you and see your NSX. Next Spring for sure. Bill
 
Olde Guy,

By any chance you have a side shot of your car? I'm interested in the wheel/fender gap with the type-r suspension.

Thnx in advance.

Henry.

The NSX-R suspension only lowers the front about 3/8 inch and the rear about 1/4 inch by my initial measurements. It might become 1/8th inch lower when the suspension settles.

This is the best I can do since the photo of the wheel area is rather dark - I lightened it before posting. I have the stock 16 inch wheels. I could send you the photo of the whole car by e-mail if you like and you can play with it in Photoshop.

Yeah I just got done Type R suspension/top and bottom chassis bars/Compliance beam and toe link mods. Taking it to the track mid Nov. I will give a detailed report afterwards. I would say that the Type R is ideal for track cars. If you are planning on tracking your car regularly then I would go with the Type S(Zanardi) set up.

You mean: "If you are not planning on tracking your car regularly then I would go with the Type S set up."

Right?? I agree. And I look forward to your report as well.

If anyone is interested, I have the Zanardi springs over Koni shocks sitting in my garage (springs are already mounted).

Make me a reasonable offer...
 
Count me in as another track junkie who is impressed with the NA2 NSX-R suspension.

I finally had a chance to test the newly installed suspension at the track today with the SO3's mounted on the Prodrive GC-010, in my previous times that I ran the same wheel tire combo with Tein's the car lacked lateral grip, I had suspected that due to the low offset of the wheels that the Tein's did not have sufficient travel or that one or more of my shocks might have died.

With the same wheel/tire combo and the NSX-R suspension the car handles great, it has tons of grip and handles very smoothly and predictable at the limit ===> lower laptimes :biggrin:

Can't beat all that R&D time that Honda put in with the NSX-R at the Ring :wink:

Ken - I also am using the SO3s with the NSX-R suspension and think that they are terrific. I have the 1994 stock wheels and use oversize 225/16 and 255/17 inch. I think that they softened the ride a little.
What sizes tires are you using? Thanks,,,Bill

I just added the type r suspension and front sway bar to my Zanardi. I already had the rear suspension beam and tie-rod ends. I bought everything from SOS.

The car corners flatter but it rides like an iron-wheeled wagon.

White94 - You are OFF TOPIC. Furthermore you have informed us about your new suspension on another thread.

This thread is about the NSX-R suspension. Would you please delete your posts so that people searching in the future for information about the NSX-R suspension don't have to wade through your bull____?

I suggest that you start your own thread about the Koni/Zanardi combo if you have anything to say. You are in danger of becoming a posting whore.

AND YES, I HOPE THAT THE MONITORS READ THIS! MAYBE THEY CAN DO SOMETHING ABOUT YOU INDISCRIMINATELY POSTING EVERYWHERE WITH NOTHING TO ADD TO THE TOPIC. YOU AND I JOINED NSXPRIME AT THE SAME TIME. YOU HAVE 1121 POSTS AND I HAVE 128. THAT SAYS IT ALL.

Gladly, thanks for phrasing your request so politely. Congratulations on being the first person to make my ignore list.
 
Hey Olde Guy Congratulations on the new suspension, I look forward to seeing it in the spring. My car is still not done, if it's not ready soon I'm going postal.

:wink:

Hi Bill,

The SO3's are 215/40 17's and 275/35 18's, the wheels that I am using are 17x7.5 35mm offset front and 18x9.5 39mm offset rear with a 5mm spacer => 34mm offset.

In addition the hat's on the rotors of the BBK are about 5mm wider than stock. So overall the front and rear track widths of my NSX are significantly different from your setup.

I also have the NSX-R lower chassis reinforcement bar installed along with the the Dali street/race sway bar set to full stiff up front and the rears are set one away from softest.

Ken

BTW: docjohn posted on an earlier thread that once I tried the NSX-R suspension I probably would not look back at the Tein's. He was right, what Tein's? :biggrin:. Let's see what I can do at Sears with the NSX-R, with SO3's and Tein's I was running 1:58's, so maybe with the NSX-R suspension the laptimes will drop by 2 or 3 seconds (wishful thinking, hehe)

Ken- I would love to have that much rubber on the rear of my NSX.
Please give us some follow-up and let us know how you do! Good luck,,,Bill

96redT - I get that "iron-wheeled wagon" feel on some roads too - not so pleasant. Have you taken your Zanardi to the track since the suspension change? That is the compensation for me for having the rough ride at times.
Bill
 
well I WAS going to give an update with the Type R suspension. Unfortunately, it cold and rained all weekend long. I think the fastest I got in the straights was 80mph :redface: I was kinda fun to slip and slide all over the place but it wasn't fast at all. Hopefully I will get another track event before the end of the year. Otherwise, I have to wait till spring. :eek:

Hi Bill,

It turns out that at the event at Infineon tomorrow the organizers will be running the NASCAR config so I won't be able to compare lap times (apples to apples). :frown:

That being said I had a track day at Thunderhill yesterday with Speedventures with the regular config and I was able to lower my laptimes by 2 seconds over my previous average and best laptimes (apples to apples comparison, same track config, only difference was track temps) with the SO3's so I'm sold on the NSX-R suspension, definetely not looking at any other suspensions unless I end up with slicks.

Lot's of fun chasing down various cars with R-compounds with street tires and getting the puzzled looks after they drop by and realize that I'm running SO3's. :biggrin:, hehe.

Now I need to put a wider rubber up front for more speed and less understeer through the sweepers to make use of that extra grip on the rear end with the NSX-R suspension :wink:

Ken

Ken - That's great! Glad to hear it. I was at a three day BMW DE three weekends ago at VIR including an instructors' clinic on Friday. First time for me with the non-compliant rear beam and toe links in addition to the NSX-R suspension. I was in their "A Group" (just below instructors) on Sat and Sunday at the North Course.

By Sunday's third Session, I was leading the pack of various M3s with R-compound. I was pulling away gradually and no one was catching me. I was on SO3s like you, but : 225/16 and 255/17. It is a great feeling!! I couldn't do that with the stock suspension.

And that's my thing: drive it to the track, run it and drive it home.

Quick update, NCRC decided to run the regular config for Infineon today instead of the NASCAR config.

Bottom line, laptimes improvements over 2 1/2 seconds :biggrin:

Ken

BTW: Bill I'm also thinking about going 225 up front, because of the extra track due to the BBK, otherwise I would go for 235 instead :wink:
