    GR86 GRBLUE86's

    I only get it on track once a year on average (anti-clockwise tracks or if it's wet!), so on-road behaviour is more important for me. Obviously depends on damper settings but would you say B-road ride quality is better / same / worse with the MeisterRs?

    GR86 GRBLUE86's

    How do you rate the MeisterR ZetaSport coilovers? I'm thinking about going for these hoping for a bit more composure at the rear end on bumpy B-roads. Already have the MCA traction kit but it's not enough. I guess you have 5kgf/mm springs all round? Does that make the ride even more choppy...

    GR86 Pros and Cons of 10mm spacers

    I fitted 10mm spacers on the front only to give clearance to AP calipers with an old set of 17" wheels I use on track. Don't whack them with a lump hammer like Kevin Vo! The impact is all going into the wheel bearings. A ball joint splitter will remove and refit them without abuse. No negative...

    GR86 BC Racing coilovers experience?

    Looks like you're aiming for a high g, track biased setup - is that fair to say? I have a bad case of oil surge paranoia, so have gone in the opposite direction by using low grip tyres (very old PS4s). I'm not chasing lap times - aim is to get neutral balance (it's pretty good now), progressive...

    GR86 BC Racing coilovers experience?

    Really interesting! Front end feels fine to me - just needed more camber to dial out the understeer. Stiffer front ARB hasn't had any negative effects on the front end but has helped with stabilty on initial turn-in. Rear end has sharp vertical, longitudinal and lateral movements under power...

    GR86 BC Racing coilovers experience?

    That's harsh! Nothing against Lidl or Bordeaux but the GR is at least a Chilian Malbec :LOL: I'm still on the original PS4s so will definitely be trying something else when the time comes to change. I'll have a play with tyre pressures next time I'm on track but the behaviour on smooth tracks...

    GR86 BC Racing coilovers experience?

    Thanks for the feedback! Fitted the MCA traction mod last year and that does make a small improvement. Also have a stiffer front ARB, Pedders front top mounts and (as a bit of a punt) BRZ rear spring dampers from a US ZN8 which have lower rate springs. All have given incremental improvements...

    GR86 BC Racing coilovers experience?

    Poor ride quality, can't put power down on bumpy roads without the rear end breaking traction and snapping out of line. Compared to the Elises and Evoras I'm used to, the damping feels crude. Less comfortable and less composed on road and track

    GR86 Deep Sumps

    Have any of you with the FD sump fitted a Tuning Developments manifold? Either EL or UEL.

    GR86 BC Racing coilovers experience?

    Has anyone tried BC Racing coilovers, either BR or DS series (or others)? Curious what effect they have on ride quality, composure and traction on lumpy B roads. All are weak points on the GR so looking to make some improvements.

    GR86 Deep Sumps

    Anyone here done any data-logging of oil pressure on UK circuits or done any oil analysis to assess the risk of pressure drops during track day sessions? Also, has anyone actually seen any bearing damage? I've not heard of anyone in UK that's had a problem but would be interesting to know.

    GR86 Deep Sumps

    Hopefully the Formula Delta pan has turned up now? I'm contemplating ordering one so really interested in your view on quality and fit. I'm also keen to go for the Tuning Developments exhaust manifold (equal length primaries) so need to check compatibility between the sump and manifold. Can't...

    GR86 Low temperature thermostats

    I'm planning to fit a lower temp thermostat to help control oil temps on track (and engine bay temp generally) and looking at various options: Mishimoto are off the table because I've previously had one fail shut and they're not getting a second chance! Billion don't seem to be available in the...

    GR86 GR86 on track - any member experience/feedback?

    Based on info from US, I've overfilled by 1 litre and had no problems on road or track as a result

    GR86 GR86 on track - any member experience/feedback?

    Been using mine on track and would suggest the following: As well as oil over-fill, avoid the temptation of switching to track day tyres. Std PS4s will limit lateral g and the risk of oil starvation. Oil temperature limits the number of laps you can do in a session but short shifting helps...

    All models Servicing recommendations in South Wales?

    My local dealer is FRF Newport but looking for alternatives as they don't seem able to get an oil filter [sic] and insist on lecturing me about engine oil specs despite obviously not understanding them. Anyone used the Subaru dealer in Abergavenny (Keith Price Garages)? Amusingly, they do have...

    GR86 Reducing Front End Noise

    Sound deading definitely reduces the bodyshell resonance and normal road noise. I've used Silentcoat 2mm deadening mat on the door skins, roof panel, rear panels in front and above the rear wheels and some on the floor panel under the rear seats - basically all the areas that resonate strongly...
