I was lucky enough to pick up a used set of 350 EVO Sway bars with poly bushings from JasonH a little while back and would now like to comment on them after having driven with them on for a little while.

Install was really quite easy and took about 90 minutes only because I have no air tools to work with. With air tools I see this taking 30-45 minutes. The rears were very easy with fewer bolts to remove and retighten. There is only one trick on the front and that is to remove the connecting rod at the end of the sway bar completely and flip it upside down so that there is enough bolt to actually go through the sway bar to be installed.

I initially just installed the bars with poly bushings with no teflon tape or antiseize, but found out the hard way and very quickly that it is very annoying and makes more noises than the interior on a bad day. After adding some antiseize to the bushings the noises disappered and all is well.

Does anyone know where I can get a good deal on a harness bar with harness setup? I set the front and rear to medium stiffness and all I can say is that the car is now very planted but I feel I might need that harness to stay in my seat I can honestly take turns and corners like never before with great control and no hint of the rear wanting to come out on me. I think my wife is now scarred to ride with me because I want to see just how fast I can take my usual corners. I currently have the stock springs and struts, but have the RSR Ti springs on the way which will really make things interesting. I do have LE37ts with Toyo T1-S 255/35 fronts and 275/35 rears which do help a lot. I couldn't be happier and feel that I was very lucky to pick up this special setup from JasonH, thank you, for a great deal. I say special because this set is a little different than the rest I have seen. The attached is a pic on JasonH's car before being removed. I will try to get a pick on my car from the rear this week. Anyone see the difference

 

Nice. Let us know if you feel a difference.

 

What kind of jack stands are those? The ones I have don't fit the Z.....

 

I do not know as the pic is from JasonH just before the sways were removed to be sent to me. He may be able to answer that question though.

 

Are you talking about after the RSR Ti springs? I anticipate the ride to be tight, with great cornering and less bounce. Hopefully I will not be scrapping the front end all over town.

If you were referring to after the sways, then I can definitely say it was worth it. If you want to keep the stock height yet improve body roll and cornering ability, these babies worked quite nicely. Keep in mind that I have the poly bushings and wider tires as well. Together they all contribute to the results. I honestly am considering a harness setup now. The cornering ability is sick and I have to hold on to the steering wheel a little tighter and prepare my body for turns more or I feel myself rolling instead of the body, and that is only on the medium settings front and back. With the RSR springs and a drop I might be able to get away with the stiffest settings. We shall see.

Hi what is Medium with Your Track Bars.? Ratios on each hole, Etc.


I have Hotchkis Sways - I'm a mule!

Front 58% above stock
Rear 65% Above Stock

Front Middle hole
Rear Soft Outer Hole

I just go to a turn - get off the gas and turn

For $250 buck list I can't complain

Cheers Amy -

 

Theres no doubt that the Hotchkis products are a great bargain, but I for one do not believe their posted numbers. If you look at the numbers 54%, 92% and 146% for the rears those are huge numbers for only being 1mm larger in diameter than the 350EVO bars which are solid. If you look at the numbers on the front compared to the Cuscos which are the same diameter but solid, the Hotchkis again are showing much larger numbers. Just doesn't add up in my book and Hotchkis doesn't explain their numbers. Dwnshift has already given us the lbs/in for the OEM and 350EVO bars. It would be nice to know the actual numbers for the Hotchkis bars as well to make sure their math is correct and to see if they are using the same OEM numbers.

 

Oh btw,

middle up front is 1225 lbs/in OEM is 1100lbs/in

middle in rear is 475 lbs/in OEM is 380lbs/in

 

I'm going with the same suspension set up. RSR Ti Downsprings go on this weekend. And, I will do the Evo Sways and Koni shocks later on this year.

Nice choice man!

 

Thanks, I will be installing the RSR Ti springs this weekend also
I originally wanted the regular RSR springs and then Gruppe-S had such a great offer for the Ti that I simply couldn't refuse. I have considered the konis as well but wanted to try the springs first to see if the konis would be needed later since I wanted a small drop anyway.

 

I don't know who to believe on rate #'s. I like my Cusco's for track use. See avatar.

A lot depends on how hard you REALLY drive.

Going to Mid-Ohio in a few weeks where Hotchkis Sways, Cusco's and EVO's will be compared. Maybe some others too. Will be interesting to compare. I'll let you all know the un-scientific results.

 

Cool, sounds like a lot of other my350z members will be there as well. I have been trying to decide between that event and the Z Attack IV in Nashville, TN. Either way it sound like I would get to meet Doug at Crawford and some others. I am lonely up here in Iowa with nearly no Zs on the road. Mine is still the only Lemans Sunset I have ever seen in person. BTW, where is the info on the Mid-Ohio event??

 

I started a thread a while ago in Race/Road. Search

I think I have a link handy though:

COME ON DOWN!!!!!!!

 

We are switching bushing suppilers at the moment. Shoot me an email and I will get you a new non sqeaking set. I should have some of the rear sets in very soon.
I have the new ones in right now with no lubrication and there isnt a single peep.

350Zs are going to be like flies on poop at the Mid-Ohio event. Can't wait... I leave in 3 weeks...

 

Hey zzzya. Glad to hear you like the 350EVO sways! They are sweet and I sure am going to miss them while racing T2 this year. Hopefully SCCA will approve them in the near future.

BTW, If you're going to make the trip from Iowa, you need to hit up Mid-Ohio....it's one of the most challenging tracks to master. You'll have a blast. From the posts, sounds like you'd have a TON of "Z-Company" at the NASA event on 4/2...I'll be there too!

Drive on!
Jason

 

ZZZYA:

Humm, I guess I can print this thread out... And take it over to the Lead Engineer and let him reply.. I guess solid iron bars and Hollow Thick Wall Chrome Moly is what we are discussing here.

Light yet Strong, Heavy yet Strong.. Flex vs no Flex. Track vs Road
Ying Vs Yang, Curry vs Atkins. Beer vs Becks.. Ha ! He ll I don't know...

Cheers Amy -

P.S. Pretty cool pharmacist - I'll have to get back to Iowa and we can go shoot some pool.

 

I agree and have wondered the same thing. And frankly, I'd worry that some of those numbers would effect the suspension's ability to act independently, a problem when you go too stiff with sway bars (not saying it's the case, but it happens at a certain point). But my thinking moves in a slightly different direction. Given the same outside diameter, a hollow bar can actually leverage pretty close to the same amount as a solid bar. And the metal used in manufactuer has no bearing on the numbers since all metals have the same stiffness. Now that being said, still how are their number so high? Well remember how these adjustable bars work. You adjust them higher by moving the end links to mounting holes on the bars that are closer to the part of the bar that span's the car (best way I can explain it, sorry). It's a leverage principle. Thing is, just how are they moving the 3rd hole so far away as to leverage those numbers? I had a hard time getting my Cusco front bar into the stiffer setting, how could one get greater distance for greater leverage, I don't see how it could reach to do the numbers.

Even though, the numbers kinda make me go hmmmm, if I were buying bars here and now, given their diameter specs, adjustability and price, I'd try the bars never the less. If I couldn't find happiness, I'd resell them and move on.

 

Dan - talk to Wld350Z - He is the Bender.... and Has the mule..
For You...

Zzzya,

Nice! COME TO MID-OHIO. Like the man up top said, Z's (including me) will be like flies on poop there. Also, if you are looking for a harness bar, DO NOT BUY ONE NOW. There is the potential for a new harness product very soon. As I understand it, the prototype is in testing and it is the last version if all goes well. You will see it when it comes out. Hell, if you come to Mid-Ohio, you will see it.
