weinelm Posted February 23, 2006 Share Posted February 23, 2006 The local Toyota garage did my wheel alignment last year. I'm wondering whether to go back to them this year after I've changed my suspension bushes? Printouts from last year attached. Coloured pictures and numbers... all look very nice. But I don't really know what I'm looking at! Do they know what they're doing? Quote Link to comment Share on other sites More sharing options...
carl0s Posted February 23, 2006 Share Posted February 23, 2006 Hmm, impressive. What did they charge? Quote Link to comment Share on other sites More sharing options...
imi Posted February 23, 2006 Share Posted February 23, 2006 is the caster not adjustable Quote Link to comment Share on other sites More sharing options...
Soonto_HAS_soop Posted February 23, 2006 Share Posted February 23, 2006 Wonder why they had to correct there computer printout to show correct castor measurement on the retest? I would suspect that they had trouble adjusting it, so didn't, then just hand modified it to make you feel happy. How much did they charge you BTW?

RICHARDA Posted February 23, 2006 Share Posted February 23, 2006 I had mine done just like this about 3 years ago at my Toyota dealer and they only charged £25 - I don't think it required much adjustment though. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted February 23, 2006 Share Posted February 23, 2006 No, far too much rear camber, not enough front caster. Take it to someone who actually UNDERSTANDS geo, and their implications.... Quote Link to comment Share on other sites More sharing options...
Soop Dogg Posted February 23, 2006 Share Posted February 23, 2006 So just what are the correct settings? I'm intending on getting mine set up this year and would like to tkae my own set of number with me. Chris, can you assist please? Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted February 23, 2006 Share Posted February 23, 2006 The correct setting vary, dependingb on tyre size, intended usage, spring rates, arb's fitted, blah blah. Just as there is no de facto tyre pressure for ALL tyres, so there is no de facto geo setting. The settings I un on my suspension kit would be inappropriate on perhaps another set up. Not much help am i? I ALWAYS put a lot more caster in though, than that. The rear negative will wear the inside tyre edges like hell. Too much for even a track day setting.

carl0s Posted February 23, 2006 Share Posted February 23, 2006 So, is it possible to adjust caster on the Supra? I just can't figure out how you might tilt the strust forward/backward, considering that the top mount is fixed and the wishbones don't move forward/back, do they?? Curious..

The car doesn't have struts. The spring / damper angle is irrelevant to the castor angle, it's not a McPherson strut set up. The top mount position is irrelevant for the same reason. The wishbones will move forward and back. Quote Link to comment Share on other sites More sharing options...
carl0s Posted February 23, 2006 Share Posted February 23, 2006 ah, I see.. so it's all down to moving the wishbones. I was thinking that the spring/damper combination was called a strut, guess not eh Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted February 23, 2006 Share Posted February 23, 2006 Should only be called a strut when it's a McPherson strut, IMO. Quote Link to comment Share on other sites More sharing options...

Furry muff I just heard it referred to as a strut once before and it kind of stuck. So, having just looked up McPherson struts on wikipedia.org, I now understand. I had somehow thought that a McPherson strut setup was something good, but it seems the double wishbone is far superior for sports cars Quote Link to comment Share on other sites More sharing options...
weinelm Posted February 23, 2006 Author Share Posted February 23, 2006 Hmm, impressive. What did they charge? Actually not that much - £40. However, from what CW is saying I think I'll be taking it somewhere else when I get the bushes & rear wheel bearing sorted out Quote Link to comment Share on other sites More sharing options...
weinelm Posted February 23, 2006 Author Share Posted February 23, 2006 Thanks for all the info guys. The correct setting vary, dependingb on tyre size, intended usage, spring rates, arb's fitted, blah blah. Just as there is no de facto tyre pressure for ALL tyres, so there is no de facto geo setting. The settings I un on my suspension kit would be inappropriate on perhaps another set up. Not much help am i? I ALWAYS put a lot more caster in though, than that. The rear negative will wear the inside tyre edges like hell. Too much for even a track day setting. Yep edges on my last set of rear tyres were completely gone! That aligment was done with a completely stock suspension too. Now I've got Bilsteins on it's time to get it sorted properly I think!

carl0s Posted February 23, 2006 Share Posted February 23, 2006 That is cheap, but I'd rather spend the right money on having it done right. Every place I've spoken to (tyre specialist in Manchester, Specialist Mercedes repair-shop in Trafford Park, and Chris Wilson) have quoted between £170 and £200.

Chris Wilson Posted February 24, 2006 Share Posted February 24, 2006 You can't do a full geo properly for 40 quid. I charge over 3 times that minimum. 40 quid is more like they have done just the front tracking.It takes me over an hour just to set thr gear up.

kosmic Posted February 24, 2006 Share Posted February 24, 2006 The wishbones will move forward and back. Chris, how would you do that though? im guessing that the lower wishbone would be adjusted at the hub or at the subframe end?? Quote Link to comment Share on other sites More sharing options...

Chris Wilson Posted February 24, 2006 Share Posted February 24, 2006 Chris, how would you do that though? im guessing that the lower wishbone would be adjusted at the hub or at the subframe end?? The stock set up has adjusters on the bottom front wishbone, nothing odd, trick or unusual in it, even 60's American "Yank Tanks" had a similar set up.
