Post #1
Always a few threads about Renault Sports on here as they seem to be a kind of natural progression from a 6 these days, so thought I’d put a bit of info about mine on here in case anyone was interested in how they respond to tinkering …Spec wise, I have spent a lot of money on maintenance as of late, not necessarily because it was broken, but because there is nothing worse than spending £200 on a track day to then break down after 30 minutes. As such, in March I spent good money on the following:
New cambelt/auxbelt/dephaser, PAS pump, alternator, Brembo HC discs, Goodridge brake lines, Dot 4 fluid, engine oil/filter, pollen/air/fuel filters, & finally the removal of the aircon with a Pure Motorsport aircon delete kit
Modifications wise, it’s a combination of things that I know have worked on my previous clios, along with a bit of trial & error on the suspension front (ie fitting of products then testing on trackdays). Result is a car that imho handles fantastically, pulls strongly & is most importantly. FUN
As it happens, the car was also back to back tested at Bedford a couple of weeks ago, just to see how it compared to another friends track prepped 172 cup:
Essentially, Ollie's car was apparently more stable overall, & quicker through the slower speed/tighter corners, whereas mine was a wee bit more edgy/rolly/tail happy & quicker through the faster stuff. Clearly my additional front camber is losing me grip in the slower stuff, but combined with the rear ARB, im getting more front grip/rear adjustability through the quicker stuff.
Speed wise, Ollie's pulled better from low down, but tailed off after 5.5k, whereas mine was a bit flat, then felt like it really pulled hard from 5k to the red line. Mods wise, we both have a JMS remap & V6 airbox/Pipercorss filter, but Ollie's benefits from matched inlets & a de-cat as well, which imho suggests that mine is still a little strangled, giving the impression that it really comes on song from 5k (5k kick, etc). With Ollie's inlets & de-cat allowing the car to breath better from low-down & smoothing out the power delivery.
FYI, tyres & brakes are the same, ie R888's @ 28psi hot, with CL pads, Brembo HC's & braided lines. In addition, both cars run Bimarco Futuras's, with similar levels of rear strippage, ie just the rear seats/parcel shelf.
Now for me, i find it really interesting how slightly different approaches to suspension/engine breathing setups make such a massive difference to the feel/drive of what is effectively, the same car. Two sides of the same coin so to speak.
For comparison, the handling setup is now very similar to a 106/306 in that there is quite a lot of on the limit throttle adjustability (LOOS), just with considerably more grip/speed being able to be taken through the corners. The Whiteline ARB removes the tendency for slight understeer in the Trophy on the limit, the result of very hard front Sachs/softish standard rear Trophy dampers. Steering wise, still nowhere as pure as the 306, but decent enough.
And now for the spec, & a few pictures
