Replacing Rear Trailing Arms Widen The Track

[jdman 1 1 Cars]

I am rebuilding my race car and want to widen the track of the car, i know the GTI-6 trailing arms fit the 205 beam but are hard to find. Does anyone know the extra width i would get with the 306 hdi or the zx railing arms would give me,

why do you want more rear width?

 

how wide is the front?

 

306 & xsara arms are easy to find.

 

its the hubs that add 9mm per side.

306 hdi arms are the same as the GTI-6 so they'll give the same width increase by approx 9mm a side but the ZX doesn't give you anything more than the original arms afaik.

 

Xsara arms give the same width increase as the 306 GTI-6 / hdi arms if you meant Xsara rather than ZX.

 

I've a set of hdi arms if you're stuck, put up a wanted ad & we'll take it from there.

It's a backward step. What you pick up in track and neg camber, you loose with neg toe in. Far better off fitting 306 stub axles to your GTi arms, if track is what you're after. Better still, get Bridgecraft to mod your arms for neg camber & +ve toe and fit the 306 axles. I run that setup but have 405 driveshafts.

I run that setup but have 405 driveshafts.

so roughly +30mm per side at the front and 9mm at the rear.

Sorry, I don't run 306 length axles. Bridgecraft does supply new axles. However, I turned up some longer axles, 25mm wider per side.

 

The hubs don't make the track wider, it's the spacer for the ABS used inconjunction with the longer axle which make the 306 track wider.

Did you not use the longer axles I sent in the end peter?

 

Some 306 arms are actually slightly wider too, only a mm or 2 but they are.

 

I can make up custom axles and spacers to fit standard arms or as peter says I can machine your arms for different geo and widen them if needed. Drop me a pm if I can help.

[petert 585]

Now I'm even more confused. I have the axles you supplied but I had to turn up a pair as we had a race whilst waiting for the axle package to arrive. Thus I haven't fitted that pair yet. The new longer axles are in the other two pairs of arms.

 

Interestingly, we found inconsistencies between 306 and 205 hubs. Enough that we added another 6mm of spacer to the 205 brakes.

Haha! Yeah, I've seen discrepancies in bearings too! Some cheaper bearings I've seen are that short they won't bolt up properly.

Sorry for butting in here. I'm running the wider 306 setup on the back. What's required to swap this back to the non abs setup? Does the whole setup need to be swapped over? I'm running a 309 beam and 7J wheels and fed up of catching the rear arches.

[Tom Fenton 1,540]

205/309 stub axles, caliper bracket, seal spacer, rear wheel bearing, brake disc. All straightforward enough to swap over.

[j_turnell 136 3 Cars]

I thought as much, wasn't sure if I could use any parts off the 306 setup. cheers

[welshpug 1,655]

caliper bracket can stay, only difference is the abs hole and that it locates on a spigot on the 306 arm.

Hi thanks for the responses, the reason im widening it is that im putting a maxi kit on it for next year and want to bring to wheels out. I took a heavy hit on the rear quarter panel at the end of the year. So the plan is to do it up over the winter with the kit thats the reason to widen the track.
