Bigger swaybars

[wynode]

Hi,

I currently have 24mm front and 20-22mm rear adjustable whiteline swaybars.

Just wondering if you make larger rear bars (say I wanted to upgrade to a 24mm+ bar) and how much I can increase the size of my rear sway bar without having to upgrade the front bar.

Thanks

G'day,

I know its a secret but could you just offer a hint as to what we are discussing here ;) Also, could you provide info on any other mods to your suspension and power output etc.

Hi,

I basically want a bigger rear sway bar (larger than my existing 20-22mm adjustable whiteline item) and was wondering if you make anything larger.

I know you had a 27mm bar on your EK4 test civic but i'm not sure if I want something that big.

Other mods include lowered springs (1.5 inches) and castor kit.

Anyone?

G'day Wynode,

I take it that you are referring to a Honda EK Model Civic, and that you currently have a front caster kit and Control springs.

These vehicles either came ?with? or ?without? front and rear swaybars.

If your car came with OEM swaybars then we have the following items available for your chassis:

Front BHF52 27mm fixed rate replacement bar and for the rear we have:
BHR46 18mm replacement bar, BHR46Z 20mm Blade adjustable kit, BHR46XZ 22mm Blade adjustable kit.

If your car did not have OEM swaybars then you can fit the following kits:

Front BHF56 24mm fixed rate front bar kit, and for the rear we have:
BHR76 18mm fixed rate bar kit, BHR76Z 20mm Blade adjustable swaybar kit, BHR76XZ 22mm Blade adjustable kit.

Full details are shown in the Fact Sheet - a link is here:

I suspect that the 27mm swaybar you are referring to is as noted above.

A heavier rear bar could be manufactured but problems with the mountings etc may well occur.

Hi Peter,

I think you have misunderstood.

I have an EG 4 door Si and already have the front 24mm front and rear 20-22mm adjustable whiteline swaybars & castor kit.

I'm looking for a BIGGER rear sway bar than the 20-22mm adjustable one that I have and was wondering if you can make one up and if the existing whiteline heavy duty mount kit (tha I have) can handle this bigger sway bar.

Thanks.

G'day,

I'm not sure that I have "misunderstood" :rolleyes: but rather a bit confused. I don't think you mentioned that you were referring to a car let alone a Honda one ;) and as for model, year of manufacture body type etc - it would appear that you have neglected to mention this info, - I just took a guess because you mentioned 'our' EK with 27mm bars :confused:

I suggest that we go back to the start. It would appear that you currently have the largest swaybars that we recommend for your car - that being BHF39 24mm fixed rate front and BHR77XZ 22mm Blade adjustable rear bar. I trust that you have the heavy duty rear swaybar mounting kit installed with this bar.

If you are requiring a larger rear bar I suspect that you may have a front to rear balance problem that is more than likely based on poor adhesion resulting in inadequate grip. If this is the case -then I suggest that you consider your alignment setup prior to considering larger swaybars. I again note that you have Control (low) springs and a front caster kit.

To take advantage of your existing spring rates and the added rate of your bars, you need to 'be able to' plant your tyres on the pavement to maximise grip. So, prior to increasing the size of your swaybars, I suggest that you consider the following:

Front camber Adj kit KCA378
Rear camber Adj Kit KCA370
Front swaybar end link bush kit W0001

And to hold it all together when the chassis is dynamically loaded add some chassis stiffening:

Front strut tower brace KSB570
Rear strut tower brace KSB525Q

You will then be able to set your alignment to the figures listed in the Fact Sheet for the EG. A link follows:

Your "problems" may also be related to a lack of spring control and your next best move may be to consider the shocks listed in the Sports Pack.

Ahh thanks for that info Peter, and sorry about my vagueness.

I have a EG civic Sedan with Kmac springs (shocks going in soon). I think what you have mentioned makes sense, and just assumed a bigger rearsway bar would help reduce the bit of body roll/understeer I sometimes experiance.

I should probably look at the other factors such as dampers, front strut and alignment like you said.

Is a rear shock tower brace essential on a 4 door sedan?

[Peter]

G'day Wynode,

The torsional rigidity of both the sedan and hatch back will benefit from the rear strut tower brace on these cars especially when a larger rear bar is fitted.
