1986 3.2 handling problem? - Page 2

chris,

no, its going for that and alignment soon.

the strange thing is that the problem remained before and after i started the mods.

You need to get your car on an alignment rack operated by someone who knows 911s before you can even begin to analyse any of the questions that you are asking. Otherwise this is just one of those silly Pelican BBS guessing games, like "pin the tail on the donkey......"

With all due respect, of course.

I just don't know how one can guess corner weights or suspension/frame alignment, that's all.

What brand and model tyres are on your 911? I had the same or similar experience at California Speedway a few months ago. On right hand turns, my front left tyre felt as though it suddenlly folded under. It also flet like it may have been something in the suspension. Anyway, I ditched the Michelin Pilot (M???) touring tyres that came on my Carrera and replaced them with some Yokohama AVS ES100's--problem solved! My damn tyres that are fine for a Mercedes E Class Sedan could not handle the cornering forces of the 911.

So...what tyres do you have?

mike,

interesting. i haven't changed the fronts since i had the car. they are P6000's.

Rich:

P6000's have a pretty solid reputation. The tyres may not be the culprit...

Dicster, any update on your problem

dickster · 10-01-2004, 03:41 AM

hi

no, i am expecting to be able to get it in to the garage soon for alignment - waiting for funds!

dickster · 02-28-2005, 12:04 AM

the car has now been aligned although i haven't picked it up yet (i just heard they may have found a problem with the gearbox/ limited slip diff).

the alignment was apparently way off. most noticably the front and rear axles were out of line with each other? this may have caused my problem. i wasn't aware that there was any adjustment for this?

(can't believe how long ago this thread started!!)

burns334 · 02-28-2005, 03:09 AM

I was and am still curious. Got the pelican email and there it was. Keep us updated

hasn't your car been stolen and recovered since then?

it sure has!

its a reputable shop - they setup up alot of 911's for historic rallying etc, with lots of success.

i guess we are using "axle" in a broader sense! he was saying that the wheel base left v right was different. i remember another guy had problems with that recently because his front x-member was installed out of line - but i didnt know there was any adjustment available?

i will enquire next time i speak to the shop.

Pirelli's.......

Did they mention "thrust angle"? Does that ring a bell maybe?

well, they've been taken out of the equation as the shop recommended changing them before the alignment (to match the rear bridgestones).

thrust angle? no. i should be picking the car up on sat. so will get details then. i opted not to go for the gearbox work.

dickster,
Interesting thread. You were apparently a "newbie" in 2002 when this started... have seen you here a lot since then, and this problem is still under investigation.
If I was to make a guess, I now think that your car has some unibody alignment troubles, like from an accident or such.
Anyway, we are srely all dying to hear the outcome of your latest work in this regard, best of luck!

dickster · 02-28-2005, 11:35 AM

hi bill,

my fear was the same, but they seem to be happy with the alignment. they have yet to do a thorough road test to confirm the handling is okay. fingers crossed (but i must admit to being sceptical).

the proprietor said originally that he would know pretty quickly whether the tub was bent and he hasn't mentioned it since so i assume it isn't.

kqw · 11:42 AM

I meant Pirelli's....

Yeah, I've never had much luck with Pirelli's either... overrated, IMHO. Great calendar though...;-)

Another interested bystander looking forward to hearing the results - I have read many of your posts over the last 2+ years.

Maybe we can entice you onto a track day with the small (but growing) group of UK 3.2 owners who regularly track their cars.

Good luck,
Richard

Hi Richard,

I live a walking distance from Brands so I have no excuses!

My intention is to do some more track days so who knows - I have only managed one so far! One of the major reasons why I finally took the car for the alignment was for the track, I didnt fancy going back to Brands until it was sorted - being that most of the turns are right handers!

What tracks do you guys go to?
