RT 132 brakes into ta22. What shocks? Spring perch?	Wed, 31 March 2004 05:56

I know this topic has come up alot recently,i have searched but im still unclear on what the go is, so but please bare with me. I am putting rt132 struts and brakes into my ta22(not hilux/pugeot combo)with 2" lower than standard springs I need to know: Do i have to modify the spring perch? What shock inserts do i use? (brand and part number if possible) Help much appreciated cheers tom [Report message to a moderator]

See my thread here where I answer your first question and ask your second.

The difference is 15mm. If your springs are ~50mm (ie. 2") down, your total ride height drop will be 35mm when assembled as stock. You can cut and shut the lower strut body to deliver stock spring seat geometry.

Questions to ask here, is the car going to see any track or rally work, is it your daily driver or weekend warrior. If you are not going to undertake any track work, I woukd not bother with adjusting the height of sring platforms. Order your 40mmm lowered King progressive springs, and a decent set of shocks to suit the RT Corona strut. TA22 and RA23 Celica's I have done in the past using this set up hhandle like go-garts in comparison to a stock Celica. Hope this helps, regards Chuck. [Report message to a moderator]

I'm using a linear spring at ~120lb with 30mm down. To preserve intended rake the strut must be shortened 15mm. Now 45mm bump travel is removed from ~330mm strut insert. An OEM-replacement style (mild rate) RT132 insert may bottom out under these conditions. I'd prefer an insert designed for a shorter stroke/higher rate application to prevent this.

This is why I'm looking at cut and shut on the strut body and a shorter insert to match.

I like it better than the idea of taking another inch out of the front spring travel to reset the desired ride height, and I like it better than driving about on Suzuki Mighty-Boy brakes! [Report message to a moderator]

cutting and shutting is illegal for starters well in queensland anyway while we are on the subject... what strut is shorter then ra40 strut and will still take the ra40 spring? [Report message to a moderator]

its not entirely illegal - it depends how its done. it would make most coil over kits illegal and they certainly are not. SSI - the ride height with the lowered TA22 king spring is the same as the stock ta22 actually... [Report message to a moderator]

How close to 'the same'? Did you take measurements of the length of the Corona spring and TA22 spring at any stage? I'm trying to lower the ride height as I do this, and have a matched set of Lovell springs ~ I'd like to set the rake as the manufacturer of the spring set intended. [Report message to a moderator]

SSI - the rt132 stock spring and ta22 stock spring are the EXACT same length (unsprung of course) not sitting in the strut FWIW. if someone has a stock TA22 and measures from the ground to the lip of the guard then compare : mine is 630mm running 195/50/15 tyres. the rate of the king springs is 75-170lb progressive too if thats any use. while i'm on it, you can remove some length out of the spring to suit the higher bottom shock mount, but, this will reduce your suspension travel substantially - dorikan did this with his and found his bottoming out on the bump stops - so i wouldn't recommend this. IF you shorten your strut you could look at coil overs : fulcrum suspension do an alloy perch - use an ae92 insert (i think) with this setup - (so you have to cut 40mm out of your strut) and with the new adjustable seat you can lower/raise your car to suit. also bear in mind you will need a 60mm custom made king spring to suit ($250 RRP) and its all good. re: the cutting/shutting of strut. this can be done. i don't know exactly how safe this is i know of people who have done it and had 100% success, but, i think any engineer who would engineer something like this would possibly want xrays of the welds to make sure they are 100% perfect. would suggest TIG for this kind of work and to be performed by an engineering workshop.

Yup, this is why I'm seeking to preserve the...
(1) spring travel, and
(2) ride height
...I have by shortening the strut to reposition the spring seat and use the spring I have.

Removing ~15mm from the strut with AE92 insert will require spacing of the insert to make it fit the housing, but I'm unsure of the implications of this, wouldn't want the shock to ever reach full extention and produce the effect of bottoming out.

If spaced from the bottom the full intended travel could be utilised in the bump/compression movement but not rebound/decompression movement. Probably better than the other way but still not ideal.

Basically just thinking about where in available range of travel the insert would sit at rest in this setup, ie.

!
!
!
!
! < At rest(neutral) under load
!
!

Allowing significant (adequate) bump stroke but little rebound stroke. Interesting to think whether (theoretically);
(a) the strut passes rest (neutral) position in the first rebound stroke or whether;
(b)it returns to perfect neutral in the first rebound stroke. Probably depends on interrelationship of spring rate, shock rate, and bump force. Obviously (a) is desirable and if observed the only way the insert will limit travel is in low-load events (ie. car is light (over crest) and will increase propensity for car wheels to lose contact with road sooner than otherwise by limiting available initial decompression travel.

I'm assuming damper rate is linear. Is it?

Using coilover is I think no difference, the spring platform will be positioned identically regardless of whether it's fixed or adjustable. Does allow to use uncut strut and dial down the spring platform by 15mm then use standard inserts in uncut strut though.

Any idea of cost comparison of;
1) cut and weld strut housing
2) buy coilover kit, modify strut housing to suit
I think (1) costs less and should be serviceable and safe so probably my preferred option and definately I will get an engineering shop to TIG it as I'm not driving it if it's not safe!

[/thinking]

Sorry for length and narrtive-style format. Comments welcome.
