Wheel Hoping/ maybe there's a solution

[Speed3.5]

Any issue with wheel hoping from you guys (Doc B Racing MSP) ??

I know most ppl don't like and it is annoying about wheel hop. I came across this thread over somewhere else where they came up with a bar that holds the controll arm in tension ( not that much though ) which results in elimination of wheel hop.

Now, to tell the truth i was/am skeptical about this approach but the damn thing has been proven based on the claims made from the "maker" for about 6 months from now.

What do you guys, Tom, do about this issue ???

Obviously you guys are in high rpm range most of the time in track which this issue might not be as severe as from low rpm/hi torque take off or roll.

Any input on this is very welcomed as always !!

stiffer motor mounts will eliminate it!! Also while your at it toss on a stiffer tranny mount as well

hmmm , i don't know about others but w/o upgrading my turbo i spin at any given time and i do have solid mm front and back.

here are some pic's of the kit that i found:

What's the direction of the "hop" by the control arm though? To me it looks like that brace/link is restricting the vertical motion. Would that not affect travel?

 

[cityracer]

those pics are actually from my car. it does not restrict vertical motion, just deflection of the bushings on the control arm. To be honest, it has been one of the best suspension mods I have performed. It truly made an amazing difference in my front end's performance. now smooth as silk.

where is that kit sold at?

 

[cityracer]

it's a hand made short run bulk buy item from canada.... not sure of advertising rules, so I can't direct you I'm sorry to say.

Thing is that you may want to customize this set up too. Personally I had a modified gt-spec front lower tie bar that I can no longer use as a result of these bars sub frame mounting brackets (they both attach to the suubframe/control arm front bolt)... I love these bars, but miss my lower tie bar... You may want this lower tie bar integrated into the brackets instead of the indipendant brackets you see pictured above... Again, I am referring to the brackets that are bolted to the subframe side... For this project, a little trial and error will be needed to get the bracket dimension perfect to be sure there is no rubbage and full suspension travel. Make sure you are using some strong materials too, this component will be taking a huge amount of force off of your bushings now.

Wheel hop has not been an issue on the Protege race car. However, we have urethane/delrin suspension bushings front and rear. Also, the very stiff springs we use front and rear limit wheel hop.

For street/autocross/track car set-ups I think the proposed part is interesting. My concern is that the heim joints are now basically taking over for the stock bushings, so now the suspension is near solid. Hit a few potholes and those heims are going to break.

I would think urethane or delrin suspension bushings could do the same without the breakage concerns???

...just my two cents...

any part # for those urethane or delrin suspension bushings , assuming these bushing are the one used on the control arm right ?

I had the same thinking once i saw the kit but wasn't sure if it would've been a big issue when you deal with patholes( i encounter them in big # everyday so..) the urethane would be better way and cheaper probably.

 

[MSPLIFE]

yeah im also interested in this parts # for a msp 3.5

For the front control arms on the 3rd Gens, you can get the Pedders kit:

http://corksport.com/store/category/4qc0/99p-suspension_misc.html (towards the bottom).

Mazdaspeed makes bushings for the rear control arms, but you can also get an AWR or AutoEXE set of bars (on the same page) that has a more robust arm.

I have the front bushings; yet to install...

Did you ever get them installed Dimitrios and have they eliminated wheel hop?

 

[berserker]

ask for 95 type on bushings for your trans or motor mounts. look up www.awrracing.com for more info!

Way late on the update here.

I've had them on for about two years and they have controlled some of the control arm movement to an extent, but now I'd argue that the arm itself is the next item to target as a point of deflection. However, I do not think they have fundamentally affected/improved the wheel hop.
