Another polybush advice thread!

[JoeCool]

I got those wishbones. They're oem quality, indistinguishable from Toyota official ones. Personally I'd rather have a new pattern part than a refurbished one where possible. You could try rebushing them but the large vertical bush looks like it would be 'fun' to remove. Mine have standard bushings and they're fine even with very grippy tyres. I just decided that the gains from polybushes there probably weren't worth the cost of the upgrade.

Joecool - How much did you end up paying after tax and customs fees? And how long did they take to arrive?

[Superluminal]

Ahh, just seen that ebay adds import duty to the basket. The total is about £106 on the current exchange rate.

For reference set up  I ended up fitting was:

Nearly new standard KYB dampers
Nearly new Tein S-Tech springs
Refurbished polybushed front wishbones from GT4-Play
Hammerited and polybushed rear arms
Hammerited and polybushed ARBs
Toyota camber bolts on each strut

Alignment I left FCM Motorsport in Bristol with was:
Front: Camber = -1.3, Toe= 0
Rear: Camber = -1.5, Toe= -1

Slightly more road buzz than without the polybushes, but given that it is a weekend car, nothing that is a problem. Too early to tell on the rest of the set up. Full details to follow in readers rides thread http://www.mr2roc.org/phpBB3/viewtopic.php?f=88&t=61636&p=717428#p717428


EXTRA DETAIL ADDED AFTER A FEW MONTHS: The geo changes mean that back of the car is much more controlled. Interestingly, I sometimes think that this may not be all good.  Prior to the new set up there was a lovely ability to easily provoke benign oversteer on roundabouts if wanted.  This has now gone and whilst the back still can be provoked it requires real effort and is not  acceptable on the road.  The payoff is huge confidence on flowing B-roads. 

The polybushes have started to creak, not squeak, but only happens at low speed for speed bumps.  Not an issue for me, and probably something that could be fixed with silicon spray.  I didn't upgrade the ARBs and body roll now seems to be a bit at odds with the rest of the setup!

What tyres do you have?

[Superluminal]

Standard FL wheels and tyres. Mixed set that came with the car with worn Dunlop Sportbluresponse (?!) on the front and nearly new Dunlop SP Sportmax on the rear. I'll put a set of AD08R when they need replacing, possibly going up to 195 front and 225 rear.

I would like to think that will make a big difference when you swap them out.

[Superluminal]

Yep, so everyone says. With the amount of miles I'll put on the car it will take a long time to get through them. A day out at airfield with an abrasive surface might be a fun way of taking care of that though...

You might want to keep the different tyre width front to rear no more than 10mm (i.e. 195 front and 205 rear). I found the wider rears were introducing understeer into the car set up and took a lot of further geo tweaks to reduce it. 205/195 seemed to give a nicer neutral balance.

All my opinion of course and feel free to ignore me  s:) s:)
