PaulQ Posted October 21, 2020 Report Share Posted October 21, 2020 Check colour codes on springs. Link to comment Share on other sites More sharing options...
Chukkieegg Posted October 21, 2020 Author Report Share Posted October 21, 2020 Not sure the colour coding will still be on the rusty springs pretty sure they are orginal ones Link to comment Share on other sites More sharing options...
map Posted October 21, 2020 Report Share Posted October 21, 2020 Under the bonnet - assuming it's the original - there's a factory sticker - assuming it hasn't been damaged/peeled off - and that will give you a list of the options your car was built with at the factory. If you don't find the M030 code in amongst that lot then I'm pretty sure you're on standard springs for that model and year. The other place you might find the option codes is on another sticker in one of the handbooks that was delivered with the car original - yes, you guessed it: assuming.....

jonogt6 Posted October 21, 2020 Report Share Posted October 21, 2020 My 99 2.5 just says 030...no mention of the M but it definitely has the sports suspension package fitted Link to comment Share on other sites More sharing options...
½cwt Posted October 21, 2020 Report Share Posted October 21, 2020 And standard is 029. Standard springs should have blue and yellow markings if you can still see them and M030 red and yellow. Unless you have a broken spring there's not much to gain with just new springs. But if you are doing it do get new top mounts and give the top bearing a thorough clean and re-grease whilst you have it all apart, and the bump stops could well be perished too if it is all still original. The list goes on, whilst you are taking it apart, shocks will be tired (Bilstein B4 or Koni Special Active seem to be popular options) and the rubbers in the coffin arms will be tired too. Hopefully coming tot eh end of this cycle on mine at the moment! Link to comment Share on other sites More sharing options...

They were still obvious on my old springs. Link to comment Share on other sites More sharing options...
PaulQ Posted October 21, 2020 Report Share Posted October 21, 2020 You won't need spring compressors for the M030 springs. If you can't see the paint (it will probably still be visible) try jacking up the unbroken side and see how tight the spring is. Link to comment Share on other sites More sharing options...
Chukkieegg Posted October 21, 2020 Author Report Share Posted October 21, 2020 ok thanks all have to go back to the garage tomorrow to pay the bill lol they know me and they were shutting up shop when i went to collect it so i will ask to have a quick check and see if they can see any colour codes my gut feeling is they are standard asthe only extra i know the car has is the becker radio Link to comment Share on other sites More sharing options...

You are looking for a label like this, usually under the bonnet, some times in the service book if you still have it. X74 would represent sports suspension if listed. The grid of 3 digit numbers that gives all the options fitted which you can look up at https://www.stuttcars.com/technical/option-codes/ , or get a full look up done by @T911UK and raise some funds for the forum.

Chukkieegg Posted October 21, 2020 Author Report Share Posted October 21, 2020 That sticker is defo not under bonnet so either it peeled off or its a different bonnet the sticker above I mentioned is in service book and option c16 seems to suggest UK car and code946 is leather seats and that's only 2 options listed as optional equipment so on that basis it's a base level base boxster 😂 Link to comment Share on other sites More sharing options...
K.I.T.T. Posted October 21, 2020 Report Share Posted October 21, 2020 If it's not got the 030 code, you'll have standard springs. Would be inclined to go for these: https://www.carparts4less.co.uk/p/h-r-spring-kit-981331001 Exchanged a few emails with H&R and established that the standard and "M030" style springs offered at ECP and their sister company were commissioned to H&R and are exclusively available through them. In effect they're copies of the original springs in terms of spring rates, length, and other characteristics. Do check with OPC first, but I suspect the above springs will be cheaper, and will work fine for your needs. These are "standard height" springs, so ignore any references to lowered springs.

½cwt Posted October 22, 2020 Report Share Posted October 22, 2020 Genuine springs should be around £240-250 for a pair so only a few £ more than the H&R ones which don't discount using their general discount codes (currently FALL15). I was lucky and picked up a pair of new original ones from 9apart via eBay for just under £200 back in April so do a thorough search. Porsche part number is 986 343 531 01. 504 up to 2002 (supersedes to 986 313 531 05.504 from 2003). Link to comment Share on other sites More sharing options...
T911UK Posted October 22, 2020 Report Share Posted October 22, 2020 Genuine springs are £214.45 a pair inc so nearly twice the price of the H&R pair sold via ECP ECP do have the M030 set of 4 at about the same price as 2 Porsche ones if you want to go M030 Link to comment Share on other sites More sharing options...
PaulQ Posted October 22, 2020 Report Share Posted October 22, 2020 H&R springs are very good quality in my experience, so would be fine. Link to comment Share on other sites More sharing options...
Chukkieegg Posted October 22, 2020 Author Report Share Posted October 22, 2020 OK so rang nearest porsche dealer which for me is Wolverhampton gave em chassis number and its standard suspension they don't keep in stock and are £178+vat plus delivery so think I wil be going for the h&r ones that were suggested in a reply by @K.I.T.T.

PaulQ Posted October 22, 2020 Report Share Posted October 22, 2020 How do you know someone hasn't retrofitted M030 early on in the cars life.? It's unlikely, but not unheard of, so I would do a proper check rather then going on original build details. Link to comment Share on other sites More sharing options...

From CP4L website: Quote Description: Standard height front springs (set of 2) Other Information: Standard height - VM equivalent- Standard replacement Coil springs (set of 2) Fitting Position: Front £115.64 for a pair without discount. @Chukkieegg, FWIW, it may be worth checking with ECP. They do supply genuine Porsche (VM) parts, and I got an OE window regulator from them earlier this year. When I had my 2.7, I got a pair of genuine front springs for £137, although this was back in 2017. Link to comment Share on other sites More sharing options...
