Hamish Posted October 9, 2017 Report Share Posted October 9, 2017 Hi I understand rimmer uprated springs 213265ur are for the 4a through to the 6 ? https://www.rimmerbros.co.uk/Item--i-213165UR Moss show TT4102pr are for the TR2-4 AND TR4a. http://www.moss-europe.co.uk/road-spring-set-front-race-uprated-420lbs-lowered-silicon-chrome-pair-tt4102pr.html Suggesting the springs are interchangeable across the range? Thus will the 213165ur fit my 3a as I may be able to get a pair cheap. The seller says they are 40cm which seem way to long ? Help and advice needed Ta Quote Link to post Share on other sites
BlueTR3A-5EKT Posted October 9, 2017 Report Share Posted October 9, 2017 Yes the 213165UR will fit but are different height to the standard springs when fitted. What are you trying to achieve? Lower the car? Harden the front suspension? Or both. Triumph Tune data I have says fitted standard front spring (201898) was 6.75" long plus the top spacer. rate 290 ins/lb The standard TR4 front spring (210903) without spacer is 8.75" long when fitted (remember no fitted spacer) rate 310 ins/lb ...... Does this mean a spacer is 2" thick - we would need to measure one. TT4102 are hard and low when fitted Fitted length 6.20", rate 420 ins lbs. (which looks a lot like the 213165UR from Rimmers if the 1" lower means the chassis to road height after fitting.) Brother's Sprint/Hillclimb TR2 runs TT4001 with a bit machined off the spacers to get ground clearance to meet the rules. What about fitting the lower wishbones upside down to lower the car, without reducing suspension travel.? Drops the car about an inch without loosing suspension travel. I have never done it, but am sure someone has. Have you done the Revington anti bump steer, steering lever mod? If not, think about it before messing with springs and ride heights. The camber change and bump steer through suspension movement on a standard car is quite large. It is a kit that really works. Will you be lowering the rear also?

Hamish Posted October 9, 2017 Author Report Share Posted October 9, 2017 Hi Peter. Me again doing things on the cheap. I'm looking to firm up the front. Not sure about lowering but can't hurt. I was confused about the interchangeability (is that a word?) between models given what the suppliers say ?!? And that the chap selling the springs 213165ur says they are 40cm that's nearly 16" !!!!! I have the revington steering arms (ackerman mod) Spitfire 7/8" anti roll bar. Planning on 3deg castor trunnions with tr4 shortened top wishbones and the square top ball joint. I'm going for lots of camber ! Rear is firm with uprated springs The front spring locating kit (the big washers!) are already on. Was considering lowering rear via spacer between spring and axle. This gives more clearance axle to chassis when cornering. And if I win the lottery an tran-x LSD And 185/55x15 tarmac rally tyres. Equivalent to a 4.1:1 diff Quote Link to post Share on other sites

I'm going for lots of camber ! Consider the adjustable top wishbone inner fulcrum kit from Revington or Moss. Then you have not destroyed a set of top wishbones and can go back to standard at a later date. You can then set the camber that suits you and your car best. The tyres have lowered the car as a start off. Peter W Rear is firm with uprated springs The front spring locating kit (the big washers!) are already on.

Hamish Posted October 9, 2017 Author Report Share Posted October 9, 2017 They are an already shortened and braced set of top wishbones. Source from someone who did this years ago and has since upgraded to the moss set on a rebuild. As they were happy with the shortened version I was going to try them out on the same basis. The "skinny" tyres are "under consideration" There are some awesome cars and drivers in the club sprint championship !!!!!!! Quote Link to post Share on other sites
Ian Vincent Posted October 9, 2017 Report Share Posted October 9, 2017 The front spring spacer is 2 inches high. I have standard TR4 springs fitted to my 3a but without the spacer. They seem to work and the car is level although I admit I don't drive the wheels off it. Rgds Ian Quote Link to post Share on other sites

Hamish Posted October 10, 2017 Author Report Share Posted October 10, 2017 Hi Colin I fitted the moss radiator guard http://www.moss-europe.co.uk/radiator-guard-rally-type-301644.html Their anti roll bar fittings polybushes clamps etc. As the 7/8ths spitfire anti roll bar has a threaded end in the bar I used Alfa 164 drop links that attached to home made plates bolted to the front of the lower wish bones. Cost me about £120 some may say it's a Heath Robinson approach and guess what they are right. But I'm doing all this on a budget and learning a lot along the way that you don't get with the ready made suspension kits out there. The roll bar was about £10 !!!

Colin Fairhurst Posted October 11, 2017 Report Share Posted October 11, 2017 Hi Hamish, Thanks for the info. I will look into it. I do have quite a lot of late Spitfire parts. I did fabricate my own radiator guard. I might do that again and copy the Moss one. Regards, Colin Quote Link to post Share on other sites
Hamish Posted October 11, 2017 Author Report Share Posted October 11, 2017 Hi Colin This link should give you a better idea on how it fits etc http://www.triumphexp.com/phorum/read.php?7,1344910 Quote Link to post Share on other sites
BlueTR3A-5EKT Posted October 12, 2017 Report Share Posted October 12, 2017 Factory engineering drawing of sump/radiator guard is here - pages 63 on http://tr3a.info/PDFs/1954bul.pdf Cheers Peter W Quote Link to post Share on other sites
Colin Fairhurst Posted October 13, 2017 Report Share Posted October 13, 2017 Thanks Hamish and Peter. I have downloaded the factory drawings and printed pages 63, 64 & 65. Regards, Colin Quote Link to post Share on other sites

Regards, Colin Can we expect you to go into production? Think about whether the front edge extends far enough forward to mount the roll bar to and it does not hit the bumper irons. - make a cardboard template. Consider MG anti roll bar mount straps as they are cheaper than TR/Spit items and iff you choose to change to a smaller diameter bar all you do is change the bushes - NOT redrill the mounting plate. Use BHH2000, x 2 mounting strap bracket + TMG30738SPK poly bushes (for 7/8" dia Spitfire AR bar) plus some 5/16" nuts and bolts. MG got that bit right - change the bush not the mounting bracket. link to bush range http://www.moss-europe.co.uk/front-anti-roll-bar-bushes-mountings.html I made my links out of Rose joints and poly bushes, but I guess some racing rules will not allow them.

Colin Fairhurst Posted October 16, 2017 Report Share Posted October 16, 2017 Thanks for the information. I have no intention of going into production or of rallying or racing. I just think that the bottom of the radiator is very vulnerable to flying stones etc. and since I am considering fitting a front anti-roll bar this type of guard could be suitable.
